Ok, I looked at it. It doesn't support that currently. Boo. For a long time, I've been thinking of extracting that stack behavior and moving it to its own script. (Well, really, I've been thinking of writing a TurnOrder framework, of which this and GroupInitiative, TurnMarker, OnMyTurn, etc are all clients...) I'll give some thought to doing that, and also to just hacking in a swap by name.
