Is the "Hardware Tests" -> "Tune SWR" menu item sufficient for your use case? (%voltage settable in "Protection" menu)

The SWR metering and protection are features that really make the QMX a field capable radio. However, from several outings now I’m finding that I would like a front panel means to activate a reduced power transmit setting so that I could make adjustments to the antenna tuning while monitoring SWR on the QMX.
Often my antenna is a rather high Q base loaded vertical in which small adjustment to the coil position can result in big swings in feed point impedance. I’ve been using an external SWR/Power meter which presents a 50 ohm load to the QMX while measuring SWR, but this meter is twice as big as the QMX itself and means an extra piece of equipment and coax jumper to carry into the field.
If I could, from the front panel menu enable, a “tune” voltage setting and corresponding tune mode SWR protection threshold, I could leave the external meter at home and dial in the the antenna tuning using just the QMX.
Stretch goal request: an SWR sweep around the operating frequency shown “graphically” on the LCD.
