Insert Template Anywhere On A Page From Addon

Hello, currently I'm trying to make an addon that would add embeded youtube links to a vendors description. Is there any way to add a template from the addon to that description besides using hooks and overriding the companies view template? For example maybe add template after the #content_description div or inside it.

The reason I want to do this is because cs cart doesn't let you to insert an iframe in the vendor description unless you disable the sanitize option.

You can use get_company_data_post hook (app/functions/fn.companies.php) to alter vendor description

Thanks. I managed to make it work
