Help in unit group help for each hero

[ReaPer.S]

Hi, can you help me create a trigger?
I need a trigger to automatically create a group of units where a single hero is located, in the group of units there can be no more selected heroes, if I have a hero selected next to other units and select another hero, the selection to that hero will be canceled

I hope you answer me

What do you mean by control? Players do the unit control thing (not the heroes) unless if I'm just misinterpreting your point here. If your intention is to create such units owned by a hero... you should specify more details so that we can start solving this.

I mean that in each unit group there is only 1 hero, I don't want to select more heroes in a group of units.
