Dup to Tape...Expand All?

I find that when I go to the backup sets interface for a storage group that when I need to hilight dozens of backup sets prior to 'Dup to Tape' or 'Delete', that I have to go to each date and expand the triangle so I can then select  "Disk" to perform the next operation of Deleting or DUPing.

Control-A doesn't work (nor does the Shift keyto select all)

Is there an easier way?
