Just like in COH series tanks can be ordered to attack only other tanks.
in AOE4 late games when the battle is full of 8 players and smoke coming out of the enemy siege, it becomes hard to see/click on them let alone its stupid to micro ur siege and making sure they attack enemy siege instead of enemy spears. so give us a toggle just like in COH series where u can order siege to only attack enemy siege and hold fire vs other units. it will help ALOT with the bad siege pathing and the over kill u get when 4 units attack 1 of the enemy cause you had to micro them to make sure they work.
thx.
