Filtering/Search function in "My Changes and Approval Requests"

Under My Changes and Approval Requests it would be good if you could filter most of these columns especially Involvement. I am a Promaster plus a champion for a specific group so I have to wade through so many items. I would be good if you could invert the list by date so that you can see the oldest items first. Also if a Process group folder could be added or a search function so you could locate items in this list quicker.
