Hiding Book=Removed from Hard Drive but Still Online

I'm not 100% sure if it works this way or not, but it would be nice. In Logos 4, when I decide to "hide" a book from the Library using the Settings panel, it'd be great if the books themselves would remove themselves off my hard drive, but if I "unhid" the books using the settings pane, automatically connect to Logos.com and re-download the books off the Internet. With Vyrso, I can see me purchasing and reading some books one time through the Vyrso apps or even Logos 4, but some of the books I won't want to keep in my Logos library searchable. I'll read them and want to remove them off my hard drive. So being able to "hide" books and have them removed from my hard drive to free up disk space would be great, knowing always that if I needed the book back in my Logos library, I could "unhide" the book and have it re-downloaded to my Logos library anytime. Similar to iTunes in iCloud. All of my audio files are "in the cloud", but if there's audio files I'm only going to listen to once or a few times, I can delete them off my hard drive, knowing if I ever need the file again, one click and it's there.

Thanks!
