'Drag' functionality to quickly add process into the 'process group overview'

Being able to drag processes into the process group overview instead of having to add each process by selecting it from the list of processes. Once they are all in you can then put them in the right order and assign roles to it.
This would be so much quicker, user friendly and intuitive (I have noticed that dragging a process from the left hand side of the screen is what new users of Promapp automatically try to do until they learn that this is NOT how it works)
