"Select All" and "delete all"

It would be awesome to have buttons to select all or delete all Shows/libraries/banks":

Es1. I need to delete all my libraries from my usb key and then copy a list of new ones to it. Now i should delete one by one and then copy one by one

Es2. I need to copy multiple shows to and from the usb key

Es3. I need to quickly remove some channels from a bank, it would be nice to have a “block Select” to also unpatch.

Thanks

+1 !

it would make some work easier.
in iLive there were some good ideas, also concerning the moving of scenes.
