How to tell WPJM to not use single.php template?

Hi! You almost had the answer! Look at the bottom of https://wpjobmanager.com/document/single-job-listings/ :

If you encounter issues with your single job listing page, or want to remove something adding by your theme (for example meta/author information beneath a post) you can create a new template file in your theme named single-job_listing.php based on your single.php and edit that.

So in your case, you’ll actually want to copy the code from your full-width template, and stick it in single-job_listing.php in your theme. Let me know if you have any questions!

can i assign custom post type to single job listing
if yes how can i achieve that
