Rotate Gizmo for custom editing

Rotate Gizmo for custom axis scale, rotate, move Here is my idea: I have a lot faces and i want to scale them in a custom axis. In Zbrush, it is super easy because i can rotate the gizmo freely with the ALT button. In Blender we can implement something like this maybe:

Select all the face i want, then change the transform operation to "Cursor", and then (here comes my submit Idea) while hold Alt with the left mouse button i can rotate the 3D Cursor while rotate the gizmo so I can create a custom gizmo for my modification.rotate gizmo.jpg

But, it would be more elegant without the 3D cursor to set a custom transform orientation :)

(I know, i can set a custom orientation in the popup menu, but for me it would be a more intuitive mode)

What do you think guys?
