Is it possible to use a slug for knowledge articles in a Customer Self-Service portal?

Instead of this: xxxx.powerappsportals.com/.../en-us

I would something like this:  xxxx.powerappsportals.com/.../export-historical-data-using-a-mobile-phone

I have found nothing in the documentation or settings that indicates this is possible.  Does anyone have any experience with this that can point me in the right direction?

Thanks in advance!
