Allow to share all rem that match all queries in the document

There should be an option in the share document menu to also share any rem that match any queries in the source document. Consequently, when importing the shared document, all the query rem will also be imported, ideally with a choice to either fully replicate their original hierarchy or just store them in the same rem as the imported “article”. Currently, any queries are ignored when sharing.

The motivation: since RemNote is a networked notebook, any individual document is likely to rely on a multitude of other rem from elsewhere in the knowledge base, even if they aren’t explicitly references or transcluded in it. Allowing to manually expand and refine the scope of the share would ease collaboration without requiring using the same database. See the Discourse Graph Roam extension for an example of how this might be achieved and an example user story.
