Internaly linking files for work

This is probably already a feature request -
I just discovered Deck and find it very interesting. I have been dropping some projects into my Nextcloud instance and will be using it to work on.
When I work on projects, it usually has me writing up documents with guidelines. What makes the Nextcloud tie-in particularly interesting is the file storage, document editiing et cetera. So: Is there a way to link files to the project decks? It would be incredibly powerful if I could create documents in an editor and link it up in the deck, that would be great. I can see that the sharing of docs and decks with the group would need some figuring out.
Thank you for a promising tool!
