MY product urls look something like this
The ring itself is in 3 categories, Human -> Jewellery (child of Human) -> Ring (child of Jewellery).
I want my product urls to always take the product category of the smallest child. In this particular case, it should look like
A hacky way of achieving this is to first update my product to have only the ring category. This will force my the product url to change. Following which, add whatever categories I want -- it won't affect the url anymore.
I really dont want to do this so I'm looking for a better (correct) way to achieve this. Thanks.
