So, I'm a Vanguard in the level 30s and a friend has just got the game and started playing. I've run through a few Flashpoints and Heroics with him for fun, and and to help him through until we're an equivalent enough level to team up and adventure together properly. Being tank spec'd, I can pretty much stroll through these areas taking only single-digit damage, letting him do a lot of the work while I just soak up the damage.
Occasionally he'll take a stray hit from an AoE or catch an unwanted add before I can grab aggro, and as neither of us are healers I've brought Elara Dorne along for support but she insists on concentrating on healing my 1 or 2% damage and ignoring my friend's 40 or 50% damage most of the time. Short of manually targeting my friend and clicking Elara's healing abilities on the companion bar myself for each heal, is there any way I can get her to focus on him?
Note superficially similar to this previous question, except that I want them to heal someone else, not me: How can I force my companion to focus on healing instead of attacking enemies?

As mentioned in other answers there does seem to be a priority system in place but I don't know of anyway to change that.
However a possible way to help in your situation is to set your friend as your focus target and put your companions heal ability in a keybound quick slot.
You set a focus target by selecting another character (friend, enemy or npc) and pressing ALT-F (the default binding). You will see you have a new player icon and health bar on your screen. Now pressing End (again, the default binding) will cause your next ability to target your focus target.
I haven't tested but pressing End and then your companions heal would cast it on your target.
