Ability to view JIRA tickets Assigned to me but not original reported in Service Desk

I want my customers to use Service Desk only to manage their Tickets, however, if a ticket is assigned to them and they were not the original Reporter, they do not see the tickets to Service Desk. This means that they cannot use Service Desk but must use either Customer Portal or full JIRA to respond to these tickets. This can get confusing as the user experience is significantly different, all the way down to the attribute labels.

It would be very helpful if Service Desk interface had the ability to show Tickets that the current user is either the "Requestor" or "Assigned to" that way they only have to use a single view of JIRA.
