Mass set change

I am adding my collection via import list. I was wondering if there is a way to mass change the displayed "edition". For some reason most of my Born of the Gods came in as "unknown edition".

Before I put any more of my collection up, I'd like a way to mass edit these out in case it happens again. I plan on using deck box for making decks and then pulling the cards based on format and location in my binders. But that doesn't work if something was printed in multiple editions and deckbox has the wrong one I own listed or an unknown.

The list I'm using is just number of cards next to the name of the card.
