Help with AI

Hello guys. So i have a map where zombies run by themselves, find your base, but they get distracted by towers or they go in some other places. What i need is that they focus on the wall that is holding the entrance inside my base. Any ideas or somebody who is better with AI to check the map and help me. Much appreciated)

action: Every 2-10 sec of game time.
set group = all units in playble area matching conditions: matching unit type is Zombie (or something)
set point = entrance position
pick every unit in group then do actions
order picked unit to move (or move with attacking) on point
destrou group
remove point

And what if i have many bases? I set them to find and attack the walls that hold the entrance, but they get distracted by the towers and just run around the base. Is it possible to set their focus somehow on the walls? Some kind of priority of attack? Thank you)

Create an area around the entrance. and add condition after pick every unit
if an area contains picked unit
then attack entrance
else move to entrance
