[otrs] Access to many Queues but notifications of only some Queues

Hi All I am new to OTRS and have just spent the day configuring it. Once I had my head around the terminology it looks like an excellent product. A big thanks to all who have contributed. I have created an agent/user that I would like to have full capabilities of seeing queues and responding for 10 queues. However, of those I only want that agent to receive notifications for the 2 queues that pertain specifically to him. Similarly user2 for a different few queues. In the User<>Groups, the Agent has pretty much everything ticked. I cannot see how to do this differentiation for notifications. Could someone please advise? Thanks and regards J
