Select Multiple Items from our Collection

I would like to please be able to select multiple items in my collection, sometime select all of them
and then have options for all the items from my collection that I selected, like options:

- Sell all selected items
- Select a selling price (suggested price + % extra) ?
- Update selling prices, to today's suggested prices + % extra
- Delete items selected
- Add a note in the description, to all selected items (same note for all selected)

This would be very helpful, as I have over 200K cards to place manually, it will take me 20 years to do this manually...

Please consider adding these options mentioned above, this will make my life easier and
make me want to upgrade my membership too!
