Adding Cards in Mass other than Import?

Hello all!

I am new to this site and am working on importing my collections from MTG Studio to here so that I have 1) my collection in two places and 2) so that I can start to work some trades / sales of extras.

This being said, is there a way to add multiples or sets of cards by the list other than a export / import?  For example, in the case of From the Vault: Annihilation, i couldn't find a way to select all 15 cards and just add 1 of each?  It seems I had to do them one at a time.

Also, it seems that filtering is a bit off a when I tried to add "Wrath of God" from the list, it overwrote the Beta that I already had in my set.  It seems that this is a bit finicky when adding cards?

Suggestions?
