Is there a way to add controls that controls the driver nodes?

Pose Wrangler has a possibility to add Driver Transforms, but often times those transform are locked and if click on the pose you created it can not switch to the needed pose.
It would be great if it was a possibility to add controls for the Driver Nodes as they have in Mgear RBF manager:

Or maybe it is but I couldn't find one?
