i don't think so, but you can always do VIP levels ?
but, like soul said before there isn't a way to do a BP way because peoples BP changes so quickly
hmmm, you can always make a custom Teleporter Item, something like that, and make it none tradable
Or, if you want to make a special Group like you can make there VIP level sat E.g [Level 50 VIP] and have it a group but be warned doing it wont have your instant VIP hatcher etc etc, hope this helped you
