FBM doesn't affect GeoGraft's extra bones

Imago

I'm working on a GeoGraft for Genesis that has extra bones in it, a sort of short tail with four bones.

This is the hierarchy:

Hip-
  -Pelvis-
     Bone1-
     -Bone2-
       -Bone3-
        -Bone4
 -LThigh
 -RThigh

I managed to have everything working properly but the extra bones when applying Morphs to the Genesis model. The tail works, bends and morphs correctly and the bones works fine with the ERC Freeze of the tail's inner morphs, but when I apply a FBM the extra bones attached to the Pelvis node of the GeoGraft doesn't follow the gelmetry like the rest of the rig, they "stay still" in their place while the tail's geometry moves away following the morph. I can fix it using the Edit-> Adjust Rigging to figure but I can't figure out how to ERC freeze that to save it.
I tried transferring the Genesis morph to the GeoGraft and ERC Freezing it, but the result isn't consistent, when reloading the graft the bones aren't properly aligned, forcing me to redo the rig adjustement.

How can I fix it?

The issue is that those bones have no match on the figure, so there is nothing for them to follow. You might try the other Fit To mode in the Parameters pane, but in the past at least it has not been possible to simply have additional bones adjust to the figure shape automatically rather than requiring a custom property and I don't think that has changed.

I see. So, how can I create this new property?

Well, make a custom morph for the GeoGraft and hook it up in the usual way.

It's the only method? I mean, I got about 1000 FBMs, I have to create a morph for the graft for each one?

i thoght there was another way, I see many Geograft with extra bones that works fine with everything with no specific morph involved.

I tried that, the extra bones are a bit better but still they move enough from their intended place to deform the geometry. Again the Adjust to Shape fixes it but I don't see any way to make the fix permanent since, at every scene reload, the bones are again in the swrong place.

Perhaps I need some special PA tool to make my rig work like all others in the store? For example this one https://www.daz3d.com/popobawa-for-genesis contains a tail that work correctly with no deformations with any FBM, even the most extreme, its rigging is always in place.

I recently played a bit with the Joint Editor, but this is over my head. So I am reading this with interest, maybe I learn something and somebody can help you.

Which Fit To mode are you using for the graft?

Imago

Redirect Transform but even using Auto Follow Transform the result is the same.

I finally managed to make a fully working graft with no deformations, but still the extra bones doesn't follow correctly the shapes of the Genesis model... There's a way to "lock" the first extra bone to the pelvis one?

As I can see, the issue is mainly the fact that bone stays in the position of 0% of the FBM.

I tried to ERC freeze the new channels created in the graft by applying a FBM to Genesis but it seems to not retain the fixed rigging, even doing the right steps.

I also followed many times this great tutorial but every time I make the Tranfer Utility step, everything brokes...
