Transparent area around actors, are we done with this yet?

Hi all,
Is there a way to constrain the touch of an actor to the image itself rather than the actor?
IAW- if i touch the transparent area around the actor i dont want it to be selected in the game,
I read some posts since 2011, and it seems that the maximum sensitivity we get in GS is the rectangular shape around the actor.
Has this been solved or someone came up with a work around?

thanks a lot
