That isn't currently possible, but I can certainly add that in an update shortly.

So that is on the roadmap for this plugin? That is wonderful news, happy to purchase and thrilled to use. There were a couple of options out there, but some no longer seem to function with the latest RMMV updates, and others that change all actor graphics (sprite, battler, face) use script calls where you must specify each actor in a notetag on each armor. Yours causes so much less clutter, and if faces are planned, I will just use placeholder graphics in the meanwhile.
Also, thank you for the incredibly quick response! I've been beating the horse dead trying to get the right plugin for my game ready, so much so that I ended up putting off everything else and driving myself a little crazy.
