Nope. That's removing the notification and having the computer do it for you.
It's better as is. I have input simulating exploration loosely and notified somethings up. That's better for me than what you are purposing.
You could try thinking you are perceptive enough to be alert, but not perceptive to spot it for RP.
I love RP so I'm happy to brainstorm something till your satisfied if you want.
Hmm How about this.. Since there is always going to be Reloads in this situation we take that out of account and only consider the first run through in the conversation. Do you think summons should always be considered new creatures that get a new persuasion check every time they are summoned again.
The whole idea of a perception check is to notify you of something you do not notice. So what if all the things a perception check would allow to happen (breakable wall, moveable rock, stash in a tree trunk) could happen without the check but was not highlighted or commented about by Companions.
