Subscribe to NAS shares/folders and auto download

I watch a range of TV Shows which I store on my NAS and would like to specify certain folders and auto download new TV Shows while retaining some control such as being able to specify how many files should be kept on the IOS device, or not to sync unless there is a certain amount of free space available after the sync. As I finish watching a show, I can delete the show on the IOS device and have Infuse automatically download the next show the next time I connect to the home network and I initiate a sync/download.
