[Plugin: WooCommerce] Use SKU for permalink-slug

Hi,

I got a WooCommerce-site where I have products with looong names. And so far I’ve replaced the slug (https://samplesite.com/%product-category%/"SLUG") of the permalink to the same I’ve set as SKU – but I’ve gotten pretty tired of doing that as I have to wait long until the will create without publish/save it.

So I was wondering if it was possible to change some structures in the permalinks-settings to make the SKU as slug by default…? What I want is this:
https://samplesite.com/shop/products/%product-category%/"SKU"

Does anyone know if that is possible, or if I would have to download an extension – anything that would help will be appreciated!

Also another question, when having a sub-category, can you change the permalink structure to have it’s parent-category before the slug…? Like this:
https://samplesite.com/shop/products/%product-category%/"SUB-CATEGORY-SLUG"/"SKU"

Thanks,
