Page 23 of quick start states:
You can spend your action to assist another character
in their action. The dif culty to assist is 8 with the same skill as the character you are assisting is using. For example, you want to assist a pilot. You need to make a piloting skill check of 8. If you succeed, they get +1 on their check. A character can benefit from at most one assistance. Assisting can be done without remote penalty to an adjacent character or one taking a battlestation action at a different battlestation in the same module as you. Copilot anybody?
Based on this you should be able to assist for anything, but the target will only get one benefit.
