Problem Definition
The requests displayed under "My Requests" currently have a few options to display requests that are visible to a customer.

For the reporter, the choices are, to display issues "Created by me", "Where I am a participant" or both.
For the status, choices are "Open Requests", "Closed Requests" or both.
Lastly it is possible to filter based on request type.

Due to the fact that Service Desks can have more complex setups, these options might not properly cover the needs for a customer.

Suggestion

As an administrator, I want the ability to create a filter, and have the results of this filter as a selectable option under the "Open/Closed" request in order to facilitate better displaying of customer requests.
