Heal/ reload trigger on load ability?

I would like to implement an ammo system for my ghost having the ammo replenished when loaded into a medivac, bunker or command center. I would also like to have units heal on load as well instead of a green light shooting out at their metal CMC suits to be healed. I think it would make more sense if they could be repaired and if that is easier I would implement that into my mod. Can anyone give me some guidance on how to make this happen. I think I would use the event system using triggers and actions but Im not sure how to go about it. I tried playing around with things but it seems that if tou make too many changes in the editor glitches and issues show up in the mod as ai have seen multiple times. I would appreciate any advice that could be given.

Thank you.
