Sharing saved draft of an already published page?

Is there an option for sharing a BB page draft of an already published page? Ideally, if a page is being heavily re-organized/redesigned, we would get exec approval before fully publishing those changes by sending out a preview link.

However, we’re not seeing that for BB specific layout saved changes (but not published). The BB Tools Preview Layout doesn’t generate a URL that can be shared. And the Enable Public Preview plugin only
works on draft/unpublished pages through the Edit Page function. It doesn’t register that there’s a saved draft within BB.
