Wish you could add players to your party in-raid

I love that people in this game actually want to cooperate — “don’t shoot” might just be the strongest weapon here.
What I really wish for, though, is a feature to add them to my party (just like matchmaking, up to two more players), so I can revive them when they’re down or see their health.
Please, Embark — I just want to help my fellow raiders.
