Using Campaign Agents as Models in Battle

[Unahim]

I'm trying to piece together a custom unit (for practice, mostly). I know that in Shogun 2, people sometimes used the campaign map ninja model as a unit on the battlefield. I'd like to do the same with female spies, but I can't quite figure out what table controls what model the units use? I think I could probably figure it out if I know that. (extra help is of course welcome) I'd also like to use the female spy voice overs, but that table seems to be locked in the PFM atm, oh well!

All help greatly appreciated!
