[otrs] Show only customer user tickets in Create new Phone ticket

[Петър Плосков]

Hi all,

when creating new Phone Ticket in Agent interface after filling the 
customer field I get a list of recent tickets for it's CustomerID. Is there 
a way to show only tickets for it's CustomerUser. We have customer IDs with 
more than one Customer user, so it will be helpful to know what were recent 
calls for the specific user.

Have a nice day

Peter
