Turn frame selection into a .tpl but retain drawing substitutions?

Hey all!
This issue would refer to rigged characters that have a library of mouth and hand shapes in them as drawing substitutions.
If I select a certain number of frames from a rig and turn them into a .tpl, it won’t have all the drawing substitution information that the original rig has- it’ll only have the ones that happened to be selected at the time. Is there a way to copy over a specific selection but still retain all the drawing sub information?
