Help with Wix Contetn Manager Setup

Hello!

I have my portfolio website set up on WIX and I want to use Content Manager to optimise my workflow and make it easier when I add new projects. I have used a portfolio template and it is great, however, I have a couple of projects that require a video and some of them require to have embedded links. So some of the subpages created for projects would either need to be amended manually ( i don't mind doing that). But I woud like to find a way to do it in a non-destructive workflow. I have described it the best that I could but I know that is not super clear. So if you have any questions please ask away.

Please let me know how long roughly it will take to add something like this to the page.

Also please only answer that post if you know how to do it. I don't need help with visual design is just implementing this feature in.
