Adding hands via editor created items

[RayPrancer]

I've been converting my setting (Element-Verse) to work with the sample ruleset in Herolab. I've been having trouble however getting a particular ability to work as intended.
The ability (Simian Tail, which I want to assign the unique id abSimTail) grants the ability to use one extra hands worth of stuff. I'm having trouble working out how to increase the number of hands using an Eval Script - is this currently possible? If not it raises issues with multiple systems, including d20, who have several multi-armed races.
If I've missed an example somewhere, can you point me to it.

In the Skeleton files, the number of hands is tracked via the "acHands" field on the "actor" component. You'll find this defined in the file "actor.str" and used for things like weapons in "equipment.str".
