Buried/Hidden enemies in ritual

I know the enemies that the ritual can summon are based on map monster. (What I know anyway.) Mentally I can try to be aware of the enemy types that I come across while clearing a map...
But for the love of the nine, can we please have buried/dis-assembled enemies be agrod from the start?
Its kinda annoying to run around the whole ring just to find the mobs that are currently inactive and keeping you stuck inside. The activity is mobs spawning and trying to overwhelm you. Not throwing yourself around and trying to dig them up just to kill them.
