Divi 3.0.37 & Events+

I'm trying to figure out how to make the single page event use the same design as http://procare.transitnet.work/events/ (With the header background, this was created in divi builder using divi theme)

I could create custom templates but that's not really user-friendly enough for the client, wondering if there's an easier way.

OR

Is there a way to define the link set in the shortcoded calendar seen here:http://procare.transitnet.work/events/

so I can just have it go to another custom page with the single event shortcode in it?

That would work, just not sure how to define that link.

Thanks!
