How to make a unit group follows a unit but still attacking enemy units?

[HerlySQR]

Hello, I wanna make an spell that orders a unit group of allies follow a hero, but that group can't just "move to the hero and ignore everything else" I wanna that they also attack nearby enemy units, but if there are not busy, they follow the hero, I tried with patrol, but if the hero move away, they follow them ignoring everything, I tried with attack-move the position of the hero, but when they reached, they return to its initial position, what can I do?

This shouldn't happen if you set things up properly. That behavior can be toggled by ignoring or locking the Guard Position:

I don't think I've used "Lock" before but it appears to do something very similar to Ignore.
