I'll need a team-up, not squad-up system at this rate

Most of my friends are gaming friends and I have quite a few.

My old DOTA gang, couple of guys that rotate through stuff with me, Battlefield friends, Squad friends, Broken Arrow friends, Total War co-op campaigns, IRL friends who game but we have no overlap, and a couple I play something with here and there but I have not had more than 3 friends playing the same thing with me since I was like a teenager playing DOTA.

One friend was keen for wardogs and we got a BF friend on board (he moved from COD to BF wanting slower but found Squad too slow) to try the beta. We all had a blast and agreed we'll probably play this mainly for the foreseeable future.

Now I'm getting a lot of messages from friends mentioned above, even ones I did not expect to have an interest in the game. And they're bringing friends too.

I wanted a party join system for my 3ish regular friends to more easily play together but now I'm already on 10 people wanting to group up that I know of, with an unknown amount of +1s.

By the time this game releases we'll need to populate a whole team to be able to play together.
