The following is an application to space combat scenarios:
I try to keep an eye on those I fly wing with. If they need the assistance, I gladly will target their ship and offer what ever heal or buff I have available. Is there an easier way to target your own ship (in a hurry) when YOU need to heal, or buff your own ship?
IMHO there needs to be a little easier method to be able to switch between an ally ship or your own.
