slug settings in woocommerce

Dear Math Rank Support,

I am migrating a website from yoast seo and i need to only show the first order category in the url.

E.g. if a product is in the category silk->silk-satin I need to have the url with:

http://www.sitedomain.it/silk/product-slug

and not

http://www.sitedomain.it/silk/silk-satin/product-slug

Is there a way to achieve this with math rank? The way I was doing it before with yoast seo was with using premmerce permalink manager and using the option where it uses only the yoast main category for the slug.

I have seen there is an option to remove parent category slug, but i need the reverse (only show the first parent and not the child categories).

Otherwise i would need to do about 1500 redirects… Or go back to Yoast Seo + premmerce

Thanks in advance
