Suppose we have a connection between post types 'actor' and 'movie'. Is it possible to satisfy both of these requirements?:
1. Make connection metabox visible on both 'actor' and 'movie' edit screens.
2. On 'movie' screen, connected actors are sortable/reorderable.
My understanding is that #1 is only possible if the connection is reciprocal, and #2 is only possible if it's not. Is there any way to have it both ways?
