IMHO don't bother bloating your metadata with extra columns that may be wrong next random period.
I know, but sometimes I just can't help myself
I added some of MY custom columns to the Quicview VIEW (red marks) to make deciding easier

. (As you use Calibre, you will discover the amazing amount a flexibility in its design)
BTW Quickview can respect the current VL
(not done here).
Wasn't aware of Quickview, going to have a play with it
