Make it possible to reorder/regroup items on the fly that have already been added to a current Lot Value Calculator list.

Perhaps I'm naive or missing something with regard to this subject, but nearly every time I start calculating the value of a new lot using the Lot Value Calculator I end up wanting to  reorder my list after a short time. This could be prompted when I notice, hypothetically speaking, that I missed one N64 title that should have been added alongside the other N64 items 30 entries back.

This leads to me feeling slightly frustrated that I cant somehow group entries by console, region, value, etc. after they've been initially added. 

It also feels inefficient if I decide to start removing items just to re-add them in desired groups, and yet if i decide not to then I potentially end up looking disorganized to the buyer\seller when presenting or referencing a printed copy of the lot list.
