Only one music font can be set within a single flow?

In Dorico4, is it possible to use multiple music fonts (Bravura, Petaluma) at the same time in the same flow?
Like as, using Bravura for recording the vocal section and Petaluma for recording the string section to create a staff in the same song.
Currently, only one music font can be set within a single flow?

You can only assign one Music Font for the entire project.

I don’t think I’ve ever seen a piece of music with both hand-written and engraved styles on different staves.

Thank you.
Of course, I don’t usually need them, but rarely I need one engraved for publication and another with different information and visibility for use by musicians in the studio.
At that time, I thought it would be nice to use the cool Petaluma as well.
