I realise this probably won't be implemented in BG3, but I thought I'd write it down and maybe it gets into the next game if not.
Often when I try to use lifts with my party, only a couple of them actually step onto the platform. I have to ungroup, then select each other companion and tell them to get on as well. It's common in lots of games, but The Outer Worlds gets it right - as soon as you go to use a lift, your companion snaps into a pre-defined position. I'm not sure if it's a trick and they teleport in or if they actually walk there, but they've clearly marked where one or two companions should stand.
I'd imagine you could set three positions for BG3's companions (or more if you've got extra followers) and have them try to walk there while the player character is on the platform, then resume following when the player steps off. And/or make them teleport into place when you pull the lever, depending on the realism/gameplay balance.
It's just annoying when you have to do it manually, and it would be nice to see the engine handle it instead.
