Not sure if this has been stated already, but if you wanted to control each party member individually, you could break the party apart and move each one individually. That is an option. Again, let's see what Larian can do when released.
Well, of course it has. The entire discussion is specifically about how annoying that is. Especially because: 1- You need to relink them later to move them as a whole group. 2- Once separated you are forced to move each one of them individually. You can't select multiple units and move them together... 3- ...Which also means you can't give group commands like "Jump" or "Go stealth" for multiple units at once.
