Add Bring Party to Lobby Feature

Often times with friends we often want to change modes or back out of the map, sometimes browse the menus or change something and there's lack of indication if party leader has left assuming they were not automatically added to the squad.  Adding a button to bring Party members to Lobby when confirming Exit to Menu (Party Leader only) would be suffice, as you might not need the follow party leader option from BFV realistically with Comms or Discord to communicate that.
