Yes, there is a way to do occasional half page turns with foot controls, by having 4 pedals/keys. Set half page turns for the whole piece. Then in foot pedal settings, set the 4 pedals -- "turn 2 pages" will now turn one whole page, and "turn page" will now turn a half page. But you will still be stuck swiping a half page at a time with your fingers.
