Share a draft watch design?

Is there any way to share a draft design such that another user can download it to their watch? I know I can put it up and give a preview, but it doesn’t appear to allow anyone except myself to download it to my watch. I’m working with someone else and want them to be able to put the design on their watch before it goes public.

It can be done, but it has to be done exactly right or it won’t work. I also don’t want to say on here how to do it because I use it all the time to sync my faces onto my personal account (KB9TMP) and I don’t want Facer “fixing” it. Give me an email and I’ll explain how to do it. My email address is mrantisocialguy “at” gmail “dot” com.
