Save to Nextcloud folder actions

### Is your feature request related to a problem?
This is not related to a problem but more an option that would provide a productivity gain.

### Describe the solution you'd like
I'm finding that certain types of files I get I don't save into next cloud because it's an extra step that's sometimes too hard depending on the file.

The solution I would like to see is similar to how Google Drive allows you to pin a save to action for a specific folder, so if I just saved a file to a folder called scan, next time I go to send a file it has a Google drive scan folder option available for me and I can pin it there for next time too.


### Describe alternatives you've considered
At this stage I have not considered any other alternatives as things I would think of would involve power automate or other solutions of which Nextcloud is not integrated with.

### Additional context
