Show portfolio category slug if exist in url

Hey, good people, how are you?
I have a hierarchy in the portfolio section where some portfolio items have category (that matches a parent portfolio item) for example: a single portfolio item named USA with the url: https://domain-name.com/portfolio/usa.
What i’m aiming to achieve is to show the portfolio items that are related to a category to show the category in the url. for example: a portfolio item called ny and related to category USA to have a url: https://domain-name.com/portfolio/usa/ny *it does show in the breadcrumbs like so, but not in the url.
Also i want it to have a condition that if a category is not assigned not to show the category name in the url.
How can it be done? would appreciate any kind of help.
Best regards
