Custom Post Type Category Slug?

Hello David,

You can use the custom rewrite URL to add the CPT slug to the term URL. Go to Meta Box > Taxonomies > Edit the taxonomy > Advanced tab > Custom rewrite slug. Please check this screenshot https://imgur.com/BfQ23IH

Hello,

In this case, it is beyond our scope of support. You can use the filter hook register_taxonomy_args to modify the argument of a taxonomy. Here is an example https://stackoverflow.com/questions/34977582/how-to-filter-taxonomy-args-with-register-taxonomy-args-wordpress
and following the WordPress documentation
