Welcome!

Oh, no...I'm so sorry to hear that!  I fervently wish we had such a feature enabled. It's something in development for a future version, but it's not ready to be released at this time (and it won't be an automatic feature, but rather a choice with each pattern created).

One possibility until we have that capability available is that you can store your created PDF files (for free) at a site such as Dropbox or Google Drive when you plan to work with a particular pattern. I know that doesn't help now (feeling your pain!) but it's always a good idea to have a pattern you need stored as a backup somewhere so that you can simply print out another.
