It sounds like you might be using the Pathbuilder Encounters tracker? It puts everyone's perception bonus in a fairly prominent spot without needing to actually click on each creature. You'll need to mentally add 10 though. In most combats I run, there are usually only 3 or 4 different creatures at most, so even if the total number of enemies is higher, the number of DCs you need to compare to is comparatively low.
I'm a big proponent of offloading mental effort from the GM to the players whenever possible, so I would rely on players to keep track of their own detection levels for the most part. Unless there's a big reason you want to keep it secret, just let them know who they successfully hid from and who they didn't. Or have them keep track of their current stealth score and ask them for that number when it's the turn of a monster that might want to attack them. They should usually be playing between Observed, Hidden, and Undetected, and they'll probably know which one of Hidden & Undetected they're in (presuming they're in at least one of them) based on when they've moved, so usually a player should be able to handle that bookkeeping.
My experience is that it's rare that more than one or maybe two characters will want to do stealth during combat. Outside of combat it's more common, but that's not so relevant here. This keeps the amount of mental overhead necessary pretty low.
I tend to be pretty loosey-goosey in combats though. If I've got 8 enemies of 3 different types, I'll usually try and roughly remember which one went first, second, third, etc. and apply the damage based on that. But I don't actually write down anywhere "Wolf 1" that can actually easily track between Pathbuilder Encounters and my physical battle map, and I don't doubt that I make errors in whose turn it is or which enemy is receiving damage all the time. I just let it go. The same total number of turns are happening each round and the enemies have the same total HP, so I figure it mostly balances out. My approach above works for running stealth in that context, but if you're really concerned about it all being precise, it might not work quite as well for you.
