Mobile: optional attachment sync per space

On the mobile app (android), I'd love to be able to choose whether or not to sync all attachments, or to leave them on the cloud and only sync on-demand. Ideally this could be a "per space" setting.

Example: My primary space I'd probably choose to have all attachments always sync, so that everything is available all the time. My Crochet and Genealogy spaces are very attachment heavy and I really don't need those attachments taking up space on my phone all the time. I'd like to set those in the mobile app as "on demand" so that if I need a pic or file, it can be downloaded, but otherwise i can see all the notes and descriptions and tags, but the phone space isn't being used up.
