That's exactly what the MonoPoly does!
The Monopoly service manual however gives
0.000V Down Low Adjust
5.250V Normal Mid Adjust
10.583V Up Hi Adjust
and takes the signal after the demultiplexer (and after the buffer and
possible a 100R resistor).
The octave switch in the Polysix should theoretically do the job.
