Adding Multiple Cards

Could you make it easier to add multiple identical cards whilst bulk entering.  Maybe a + & - symbol with the number of cards shown (1 +/-) so you can add and take away cards without having to change screens a load.

At present if you have a duplicate card you go to "add another" then it takes you to another page where you enter all the details, you confirm and it takes you to the card page.  To then go to where you left off you have to navigate back to the set you're adding and find where you're at.  This is at least 4 pages of excess.

Wouldn't it also look pretty if you could see how many of said card you had on the set screen rather than having to look at each individual card.
