WCFM admin page slowly load in website with 1900 categories and 4000 atributtes

I bought and am building a marketplace with your super plugins. Congratulations on your work, they are great!
1. I have a problem: the website contains over 1900 categories and approx. 4000-5000 product attributes. After entering the categories, attributes and their values ​​in the database, I saw that when I log in to the WCFM admin background it loads very very slowly … in approx. 1 min. I found that: all categories and attributes populate the page when it loads. Can’t something be done to load ajax only when we need them? As it loads now, all at the same time, it creates a long wait time for pages in the administration area of ​​the marketplace.
2. Is it possible that only certain attributes can be checked as required but only for certain categories? For example: If the attribute “product type” is assigned to a category, only the products in that category should be required, not all the products on the site?
