problem with pppoe queues

Hello I’m new.
I have problem with PPPOE queues. I have everything set , server, secrets, profile for 10/2 bandwith auto setting. and it works ok, server dynamically creates queues for new users connecting but what if somone wants 15/2 bandwith for example. im removing autogenerated queue and create new one with target IP. and it works ok untill this user disconnects and connects again, then server creates dynamic queue again and it works 10/2 again over the one that i created myself. any idea how to resolve that ?

Thanks !
