Renumbering flows

Hello Dorico users
Can anyone tell me if there is a way yet to renumber flows?
I’d like to have, say, Flows 1,2,3,4, then an invisible flow 5 [which is a section of Flow 4], then proceed after invisible Flow 5 with a new flow called Flow 5.
Can this be done?
Or is there any other way to insert unnumbered flows into the middle of a series of flows in such a way that they do not figure in the numeration of flows?

There’s no way to avoid automatic flow numbering. Your best bet is to manually number the flows as part of the flow title, then avoid any tokens that use various iterations of {@flownumber@}.

In musical theatre, I used the Work number (opus number?) token of the project info to achieve a numbering like 1, 1a, 1b, 2, 3, 3a etc. Works like a charm.

Thanks to you all. I’ll try the Work Number option.
