Renderotica

Is there a way to do this?

For the sake of context, I'm using a utility from the DAZ store that fits textures from one to the other, but that doesn't go so far as to work on grafts. The default graft UV assumes that the model it's attached to uses its own default UV, so while the texture copy script works fine the edges don't quite line up.

I'm guessing that (for example) GP-G8M defaults to G8M UVs, but that doesn't help me unless there's a way to get GP-G8F to use that UV set.
