erase all tapes in a library?

[jaypublix]

In retro 6, I was able to select all tapes and erase them in one shot. I can't seem to figure out how to do this in retro 8, so I have been erasing tapes one at a time (dragging them from each slot to the read/write drive, then clicking erase)

 

Can someone explain to me how I go about queuing up and erasing all tapes in the library in one step a la retro 6?

 

Thanks!
