Howdy Jose!
It’s nice to meet you. I would love to help you as best I can.
I have had a look at the two templates you linked to. I can definitely see some differences. The template that you would like your events to use appears to be a custom one available within your theme. In order to adapt it for events, and not generic posts, you will likely need a solid knowledge of PHP and CSS. Unfortunately no shortcodes will suffice, you need to know some programming.
To that end we have a our themer’s guide. This guide will walk folks with a solid knowledge of WP Themeing through modifying our templates, and using it you can adapt the templates to look any way you please, including matching your current theme’s custom template. If you are not a WordPress themer though, then you will likely need someone who is to create the necessary code.
Does that all make sense? Does it fully answer your questions? I would love to help, so please let me know if there is anything I can assist with.
Cheers!
