Trying to force a paired animation from specific anim files

[Fredas]

Figured I'd try rephrasing a question I've been stuck on for a couple of days now.

 

The mod called PuppetMaster attempts to make use of Arrok Lesbian stage 2 for one of its functions.  I don't know if this ever actually worked, but it's a fact that right now the result is that Arrok Lesbian stage 1 plays.  I've spent half a dozen hours trying to see if I can trick Sexlab into forcing stage 2.  I need help from an expert.

 

The most convenient solution here, assuming it's even possible, would be for me to be able to pick specific animation files for actors 0 and 1.  That would give me a lot more flexibility on how to fix PuppetMaster's bug.  Barring that, of course, specifying stage 2 of Arrok Lesbian is the best remaining hope.
