"Open in..." functionality in iOS

I want to use the “Open in” functionality within, say, Drafts or Goodreader to send a current draft or PDF to Scrivener. This works fine, so long as Scrivener currently has a project open. If it doesn’t, it doesn’t even ask you nicely which project to copy it to - it just tells you that there has to be a project open, and fails.

Can we either be allowed to make a selection of project, or at the least specify in settings a default project to copy to? (I’m not asking to be able to specify a folder for the document to go to… or for full x-callback-URL functionality… or anything outrageous like that (although they would be nice)).
