In DropBox, I was able to enable a feature that allowed selective syncing - specifically, I was able to create one folder where the contents were uploaded to Dropbox from my workstation, still stored on the workstation's local storage, but NOT synced with my iPhone, MBA, and rMB. (Other than using the 'optimize storage' feature - which I would prefer not to use as I don't have control over what does/does not sync) is there any workaround for this with iCloud Drive? Thanks!
