A suggested change to abilites

This is like a tiny thing but it has always annoyed me,

if a unit with an ability, like the explorer with the crackshot, is grouped up in formation and you set the ability to cast, the other units in the group are just stunned while the unit execute the ability.

This kinda means that you always want the units with abilites to be in a separate group but you also want to group these units in the main group as well.

As group control arent like in say starcraft or in aoe 4 where you can have a unit in 2 different group, its really annoying and can cost fights if you are trying to snipe or do aoe shots from like the haud warchief.

Can we make it so that castting abilities while in a group doesnt stun other units?
