user manager with both hotspot and pppoe

dear all
i activate both pppoe and hotspot using usermanager to controll some users, suppose a username “aa” created in user manager, then connect in hot spot from pc1, from the same pc this user connect using pppoe at the same time of using hotspot, how can i split both services in usermanager ? i mean give 10 users the access to the service using pppoe( and deny them as hotspot) and make another 12 user able to connect the service via hotspot( and deny them in pppoe).
any idea’s ? is these any choice in the user package in user maneger to spacify the connection way ?

It is not possible to specify it on direct way.

is there any un-direct way ?
