I have two lyx files.




I want to reference the pagenumber of the conclusion, for example, from File2.lyx in File1.lyx. When I insert cross-ref, it gives back Page ?? because of course these are separate documents.

Can this be done with multidoc settings?

I see many people tempted to use the xr package, but Lyx does not seem to communicate well with it. (Doesn't create aux files and requires hacky solutions).

All of the questions I am seeing asked about this topic are over 5-15 years old with no updates, so I think this is time to ask the question again, even if it has a decade-old duplicate.
