Hi @aaronrobb
Problems are meant to be solved ey 🙂
I dived into the taxonomy field code and unfortunately it looks like you wont be able to do this when you have it set as checkboxes.
It might be possible tho if you’re open to change the visuals to multi-select instead? There are some filters one can hook into but none of them are at work on the checkbox layout since that actually uses the wp_list_categories() function from WP core (with a custom walker function).
