How can I add a custom header to listings?

Re: https://theamateursdigestarchive.net/cactobiz/klyn-nurseries-inc/

Hi. I’m trying out your Lite version. Looks good so far.

I have been able to set up a main page, CACTOBIZ, and it was easy to go into the post and add a custom header.

However, I am leaving it open to auto-publish new listings. Also, it’s time consuming to have to select a custom header for one listing at a time. Is there a way to automatically assign a custom header to all listings? If not, every listing will get a very large header by default that weighs down my traffic if the listings are frequently used.

Is there a way for me to assign a default custom header to all listings in all current and future categories? I’m using the “Unique headers” plugin to control custom headers all over my web site.
