Desktop client working like android client

I was wondering why the Macos Desktop client has to sync all the files and folders? Why is it not possible to let it work just like the android App?

The difference, If I’m right, is that Macos desktop really syncs the content and the Android app just gets the folder and file name, and only downloads the file which I need.

This behaviour would be very appriciated on Macos too. Because the storage space on my macbook is limited.

Is this possible, and am I missing a feature? I’m using webdav now, but this is very slow.
Kind regards,
