League Mechanics and Spawned Mobs

Could you put minimap icons on mobs spawned by league mechanics? I've had issues w/ Strongboxes in the past where monsters spawn behind a wall or something and it just becomes really tedious to find every last monster. This is beginning to get very tedious with Abyss mechanics. (Though even with it everywhere and being dangerous and hectic as hell I am enjoying it very much so far for the most part. Maybe the biggest factor is the rewards seem well worth the risk.)
