Copy in a mirrored option

We should think to implement some kind of feature that can give us a chance to copy i a mirrored way usefull with pan tilt feature!
so we select 5 fixtures of 10 we position them, and the copy the “pan tilt “feature in a” mirrored” way so we will get a specular and perfect look!
Currently we need to select in a reversed way the fixture we want to mirror ,so we can obtain the same result,but as personal opinion it’s a long way of doing this thing!
Just a simple feature “copy mirrored”.
