No, it would be an Investigate Action that would search in a 18m radius. Search the area.
Which could easily just be abstracted into characters doing it everywhere automatically.
I'm not sure if you realize this or not, but what you've said right there is exactly what the game is currently doing that you said you don't like? The game is assuming the characters are active searching all the time, but only shows the rolls when they are pertinent. If I'm not mistaken there is actually a setting to turn off viewing those active rolls? I believe I read that somewhere else on the forums. In which case, you've got exactly what you want. Turn off the view for those activated active rolls, your party is actively rolling whenever stimulus is present, and you won't be made aware of any misses, you'll only see the hidden objects/traps if you've made the roll. Am I right in assuming that's what you're asking for?
Edit: Turning off the view for those "active checks" may be a mod I was looking at. Can't currently check game options as I'm not at home. If anybody can check on that and clarify, I'd appreciate it.
2nd Edit: It is a mod:
https://www.nexusmods.com/baldursgate3/mods/548I realize that not everybody likes to mod the game as it can cause some fatal errors, which just validates the opinion of the original post. If you are willing to mod, then obviously that mod is one you should look at adding.
