metacreator customization question

This question is for anyone who has played with adding new virtues/flaws/abilities via creating/editing the data sheets.
I'm trying to put a virtue in that will auto add required virtues and flaws when selected. One of the auto virtues is Puissant Single Weapon.
So the code that I have is ...

Puissant Ability[Puissant Single Weapon]=+1

I can't figure out how to make it auto select Single Weapon, instead it brings up the choose ability box like when you select the virtue Pussiant ability directly.

Any Ideas? or does meta creator have a help forum someplace?

I don't have time to dig, but there's a Yahoo! group.
