Best way to move scale pivot with mirror modifier There are times when I'm box modeling with a mirror modifier where I want to scale a face from the center axis (that I'm mirroring over) NOT the center of the face.

Currently I'm doing this:
Enter Edge Selection Mode and select and edge on the center axis
Shift - S to snap 3d cursor to edge
Use S then X to scale on just the single axis

Is there an easier way to do this?

Thank you.
To do this:


Switch to edit mode





Switch to edge selection





Select required edge





Shift+S --> cursor to selected
