Control Rig Unparent Root Control?

Hi, wondering if anyone has tips on how to set up an ‘unparented’ Root control to the Mannequin? I’d like to be able to rotate the Root without rotating the entire rig. (for making pivoting animations with locked feet)

I had thought unchecking ’ Propagate to Children’ on the Set Transform - Root would do it, but no dice.

For anyone else wondering - I just changed the Rig Hierarchy so that the foot controls were not children of the root (dragged them to the bottom of the stack)
