Just make sure it doesn't get confused by \newSpacingSection or a manual change 
in the common-shortest-duration (both of which I use regularly).

I would prefer an even more straight-forward input, if possible.

On a related note, something I've been asking for forever (and willing to 
sponsor) is the ability to change the bounds of horizontal spanners by duration 
— that would solve this problem easily, without need for additional voices.

Best,
