Connecting default fields from a pods custom post type to an extended post type

Hi,

I have extended the default WordPress post type to include two additional custom fields called blog_post_author and blog_post_author_bio. I have a custom post type called post_author that includes the name and bio of authors in the post_title and post_content respectively. These have been imported from another site.

How can I connect the default post_title and post_content of post_author with blog_post_author and blog_post_author_bio respectively? Essentially I wanted to show a list of authors in the Posts for authors to select. These authors that will be added under post_author.
