Remove ‘and’ and reorder how Categories list in a template.

Hi, right now I have PODs template setup to display my CPT of videos. It works, but i also have the Categories set to display on the post.

Right now I have a parent Cat called Conferences, and a child called 2019. It displays them as 2019 and Conferences.

I would like parent and child cats to display something like this
Parent > Child, AnotheCat, Parent > Child, etc, etc.
Conferences > 2019, Music, Medicines > Ibodega, etc, etc.

Is that possible?

I can’t link the page easily as you need a free membership to see it.
