Adding a custom section to "New Post" and "New Page" sidebars

I’m not finding any hooks that allow new sections to be created in the sidebar of the “New Page” and “New Post” pages. I would like to create an extension that allows you to choose a page template to utilize on the new page being created.

Hi Andrew,

You can use mainwp_edit_posts_before_submit_button that fires right before the submit button or mainwp_bulkpost_edit_top_side that fires at the top of the sidebar.
