If you are placing the character and army on the map you don't need to add a trigger for the trait just give it to the character in descr_strat.txt. Obviously the army will be able to move if /when the general dies.

This doesn't do quite the same as using super_faction setting (which is what kept the entire senate faction non-expansionist) but it also doesn't have the draw-backs in terms triggering 'senate' missions etc.
Thank you, it has been very useful!. It is a pleasure to find generous people as you .
