Manipulating multiple effects gizmos at the same time

I like the drag&drop feature that allows me to position alphas on the model surface easily and then fine tune them.
What I'm missing is the option to treat them as a group.

Let's say I put a bunch of stickers on an object and the placement is not entirely random, it would be desirable to just duplicate and mirror all of them to the other side and instantly have a good starting point there.
As it is now I can only select and move one effect at a time. So If I have placed 7 details on one side of the object that I want mirrored I will have to individually select each, flip it and manually move it to the other side.
Just being able to select all of them and performing the flipping and moving for them simultaneously would be very helpful.
