Feature request: Make folder/files online-only

I've looked through the Dropbox documentation and it seems that for other clients, like on Windows and Mac, it is possible to right-click a folder or file and select "make online-only". Could this be supported in Nautilus as well?

My use case is that I have an "archive" directory into which I am programmatically copying compressed archive files. Ultimately, I would like these files to only be stored in the cloud, such that the "archive" directory does not take up tons of space on my laptop. I tried selective sync on this folder, but that removes it entirely from my laptop, meaning that I have no way to get content into it in the first place.

So, the "make online-only" option that I have read about seems like it would do what I need, but I'm not seeing any implementation of it in this package. Thank you!

The issue names no files, tests, or entry points. Start by locating the Nautilus context-menu integration and checking how this package invokes Dropbox operations; done means a file or folder can be marked online-only without removing it from Nautilus, with behavior confirmed for the reported archive workflow.
