Move portfolio item to different portfolio

Hi guys,

First of all I want to thank you for your awesome templates and support. You have a great team of designers and coders helping us newbies.

I created a new portfolio called “1” as seen below, how can I create and move it to a new directory called “party-tours”?

on our site all portfolio’s are created in the https://partytours.vegas/portfolio/1/

so I would like to do https://partytours.vegas/party-tours/1/

I’ve seen this done on other sites but I’ve only been working in WordPress for about 2 weeks now so any help would be appreciated.

Thanks
