Customer queues

[rmaul]

Hello, i am running OTRS 3.3.6 syncing with my lotus domino LDAP and everything works great. I just finished setting up the roles for auto sync.
Even tho everything is perfect, i got to a problem that my company does not allow. When customers open up a ticket, they can pick any queue they want, like, level 1, level 2, Manager, etc... Because every group i make to point to a role, shows up for the customer. I would like the customers to only see 1 queue, called lets say "Tech Support", and the agents lvl 1 would then solve the problem or requeue for a different area. You see, the customer dosent always know which queue his problem is going to fit, and its going to be alot more trouble if i just let the customer choose his own queue.
Is there a way to prevent it, allowing customers to only pick one queue ?

Thank you in advice.

set a default queue in sysconfig.
