I am having some trouble with a 6/8 time signature that has a 3+3 pulse but many hemiolas.
As stated above, the majority of the piece has a [3+3] pulse. However, I am playing around with a lot of hemiolas and want them beamed as individual quarter notes, NOT [q, e-e, q] which is what Dorico is defaulting to.
I don’t want to go to 3/4 time because of the tempo and pulse.
And, following on from what vilnai said, your 3/4 hidden time signature can apply to individual staves rather than the whole ensemble. Use shift-m for the time signature popover, type 3/4 then Alt-Enter to apply it only to one stave, then copy and paste (or Alt-click) to other staves.
