It would be great to add a filter so I could see what cards I own that are Reserved List. Or be able to add a tag to those cards that are, so I can sort it myself.

It's not the best solution, but if you add this deck list to your account:

https://deckbox.org/sets/1420956

then you can easily check a specific card by clicking on the card and then seeing it listed under "In your decks".

Also, if you go to that "deck", you can sort it by copies in inventory, which at a glance will show you all the reserved list cards you own. However, if you don't have a premium account, then you'll have to look at each card type (enchantment, instant, etc) separately. With a premium account, you can change it to "ungrouped", so they're all at the top.
