Selective synching and/or file streaming like Google Drive

I'm currently having trouble because I had to pause synching my files (I don't have enough internal free space to sync all) so I was wondering if it's possible to introduce the option to selectively chose which folders I want to download locally and which only remain in the cloud but aren't synched locally. Pretty much every cloud provider has this feature now.

Even better is the solution Google drive has where I can see my entire folder structure locally and even open files even though none of them a permanently saved locally just streamed at the moment I open them without taking up space later after I stop using them.

That'd be an amazing feature making the creative cloud sync so so much more useful when working on a laptop.
