Allow Advanced Post Creation to Work on Editing Posts

I am excited to use the new Advanced Post Creation add-on. But it falls majorly short on being usable for most of my projects as there is not a way that I can see to use it to edit a post.

It seems like if you just added a hook to the create_post() function before calling wp_insert_post(), so that we could update the post object with an ID, it would solve that problem?
