Customizable Piles/Sections (Beyond Considering and Sideboard)

I usually start with a couple hundred cards to cut down to 99, it would be a huge improvement to make your own sections/piles to help organize the bulk. I’m considering “Main Deck” and “Considering” as sections. I’d use it for tiers and reasons they’ve been removed (cost, staples that didn’t make it, etc). I understand tags can help with this a bit, but I don’t want tags that organize my considering pile to follow into my main deck when they’re added back, and when using tags to view all my “Considering: Card Advantage” for example, I won’t see those tags at a glance.
