Basically you would have to write a function that implements your action.
The manual chapter on group actions
http://www.gap-system.org/Manuals/doc/ref/chap41.html
describes this.

Please note that for any user-defined action the cost (memory and run time) of a stabilizer calculation is roughly proportional to the stabilizer index.
