Target unreachable monsters?

[KnightmareFury]

Good evening,
so, I'm trying to figure out how to make my targeting actually target monsters that are unreachable.
Basically, I got a team who lures the monsters back to a safespot on Warzone 3, but the bot won't target the monsters since there is a wall (which you can attack through as a Paladin) in the way...
Any chance to fix it?

Thanks
