How to add criteria to the display settings when you ADD req

When you try to add a requirement from a pool of requirements it would be easier if you can filter by criteria other than the defaults (Status, ID, Community risk, etc). For example we have categories defined and using that field to sort requirements by functionality/system etc. We also have requirement type enumeration field that designates weather its a design, technical, functional requirement etc. While these fields are available for regular queries how can we bring them in to the search criteria when you click on the little green plus button to add requirements? How can we filter out of the thousands of requirements by lets say requirement type to get to the one we need?!
