How do you post the same card under different editions, for example i have 5 different editions of sol ring but the data base inventory will only let me put it under one edition. How can I change this?

1) Press Ctrl-I from anywhere on Deckbox.
2) Type in Sol Ring.
3) Click the "My Collection" tab.
4) To the right of Inventory/Tradelist, click Edit.
5) For the card you want to change, click on the set symbol.
6) Select the appropriate set.
7) Repeat steps 5-6 for each card you want to edit.
8) Click Apply.

Edit: Steps 1 and 2 can be replaced with simply clicking on the card name in any list (tradelist, inventory, deck list etc.) Sol Ring
