Dual/Poli Tonality

Hi everyone,
I’m curious to know if Dorico 3.5.12 supports Dual/Poli tonality. Just interested in exploring this composition technique.
Thanks,

If you’re asking whether you can have different key signatures in different staves, the answer is yes.

Select the staff, Shift-K, enter the key signature, and close the popover using Alt-Enter or Opt-Enter.

Thank you. This solved my problem.
