How do I add and sort items from My Requisitions?

I was able to add items to Search Results and sort search results from the Manage Requisitions screen of my existing SSP,

but it seems I can't do this from the RSSP screen.

Is there a way to add items and sort search results from My Requisitions in the RSSP?

■SSP screen: Manage Requisitions

■RSSP screen: My Requisitions
