There is no logical way of doing it since anyone who is a TL3 is automatically a member of TL0, TL1 & TL2..
One possible manual (and non-intuitive) way can be to add all the TL0, 1 & 2 to a separate group and then allow that group for category but that has a lot of problems. first being that people may attain TL3 after being part of that group and then they have to be manually removed by a group owner or admin.
