Transform constrain: add a new bone instead of reselect all of them.

As you can see in this image, my transform constrain had including alot of bones inside it.
The problem is everytime I want to add a new bone to this constrain, I need to reselect all of those old bones too. which is quite timesome.
Can we make a button so if we need to add a new bone to the constrain, we can just push that button and select the new bone and be done with that?
