Transferring pose controls along with skeleton

OVD

Hi all,

As I'm learning all about content creation I've made a custom creature (not to sell, just for personal use) and transfered a rig from a similar existing figure. That same figure had a collection of poses, and I was hoping to use those same poses on my custom creature. 

The problem I've encountered is that the original creature has several pose dials, and the pose presets use those dials for parts of the poses. As a result of this, the pose presets won't work on my custom creature since it doesn't have the pose dials. 

Does anyone know how I can save those pose presents so that they rely solely on the transformations of the individual bones rather than on the pose sliders? 

Thanks!
