[otrs] Link between Queue and Service

Hi ALL, I am looking for Service filtration based on Queue selection in Customer Panel. Customer is associated with groups. Services are linked to Customers and Queues again mapped to Groups. So i am not able to filter the Service based on Queue. For Eg: If i select queue from Customer panel, only associated service should display on that Drop down list. This is my preference. But currently service is showing all Services which are mapped to the customer. I would like to show only service based on Queue. Is there any link between Queue and Service? Is anything can we do through code? Please help me on this .... Regards, SMPM
