Override Core Templates Filter?


This question is in regards to this feature here: https://kb.wpbeaverbuilder.com/article/92-replace-built-in-layout-templates-with-your-own

So I have this setup, and it’s pulling in the custom templates from the source site just fine. My question is what if we want to filter out (not include) a few specific layouts? Let’s say I have 10 layout templates on my source site that are syncing up to all my subsites. But I only want 8 of them to sync, is there a way to choose certain templates to be “opted out” of the override?

Hopefully I explained that properly. Thank you.

Edit: Just thought of another question. I can’t seem to get the dropdown of the template categories/groups to show like in the first screenshot of the above article. Any ideas as to what I could be missing? I have added the templates to a category and given them a featured image.
