Stacked/overlapping UVs into multiple UVs.. help!

in New Users
Hi there, thanks in advance for any help you might be able to offer.
I am using Daz to make OBJs that I am texturing in C4D. When I export Victoria 6 I am finding that the UVs are stacked in a single square, this doesnt work for my workflow.
Can I change the way it exports and have each of the seven layout unstacked on individual tiles?
I know its possible to edit the UVs manually in other programs but I would like to keep all the objects in the layered layouts Daz defines.
I do not have "Collapse UV tiles" checked.

This is what the tiles look like at the moment... all overlaid.
Select by Surface ID in C4D and move them to new UV tiles, if that is supported.
Thanks, I think that should be possible. Was hoping for a way to just export as I wanted them. Is it the case that certain models do this and others dont?
Most of the Daz humans have multiple full UV squares, and up to and including Genesis 2 they all used the base square. Genesis 3 uses UDIMs to place the different maps on different grids, so I think they will show separately in at least recent versions of C4D. Other content varies in whther it uses a single packed UV square or multiple squares, few if any items use UDIMs as yet.
