Any plans to add acquisition price and date?

Hi, I've been looking for a collection management tool and was wondering if there are any plans to add acquisition price and date for inventory cards. I'm mostly interested in tracking collection value after the date I acquire cards and the only other tool I've been able to find that does this (beyond my own spreadsheets) is EchoMTG which is just a bit difficult to use.

I love Deckbox for the decks/trading/interface, but this is a crucial feature for me and would be happy to upgrade to premium for it. Thanks!
