- Select the faces

- Press "insert" on the keyboard

- Move the pivot point to the desired location (for example snap it to a verted along the edge you want to use as the pivot.

- Press insert again


Note: when manipulating the pivot clicking the little blue circle that is on a stem from the center will pin the pivot for the scale, rotate and transform tools. Clicking it a second time will un pin the pivot point. (Yellow with a circle inside is Pinned, Blue with no circle inside is unpinned).

Hope this helps
