Adding headers to the collection

Currently: Photo, Item, Grade/Qty, Cost, Total Value, Actions.

I like all of those, but I was wondering if you can modify or add headers.  For instance, Ungraded Value, Grade 9 or 8 or 7, etc value, PSA 10 value.  It might be easier to see if your card is worth getting graded if you have an idea what the graded cards are going for.  Currently, if I click on the Total Value, that information does come up, but I'd like to see it all on 1 screen, if possible.
