We have multiple pages/labels that contain https://www.example.com/en-us/page.html and with the current translation panel you would have to add an external url entry for https://www.example.com/en-us/page,html to replace with https://www.example.com/fr-fr/page.html (for each page that is linked). We have hundreds of links so it would be a nice feature to allow widlcards, regex, or patterns so you would be able to create an entry in the translation list for https://www.example.com/en-us/ to https://www.example.com/fr-fr/ so it would replace it everywhere instead of having to put the full page URL.
