Currently, every time I go to the APPROVE requests, I have to re-filter the data.  Perhaps being able to choose and modify the defaults would also work.  Right now, however, I cannot choose the defaults and there is no way to keep the filter I use most often.  It is extremely frustrating and time consuming to have to re-filter every time I move from the page.  This is true because most schedulers also wear several other school hats and must bounce back and forth between pages often.
