Extension to locate pages/posts where an extension is used

Quite often a client site has a damaged or unsupported plugin in use and it needs replacing. The last time I had this was where a client had paid for a premium version of a PDF embedding plugin and they had let the licence expire and no longer wanted to pay for embedding a PDF. So the task was to find all pages and posts where that plugin has been used and install a free PDF Embeder plugin.

But finding the pages/post where it is used is a pain but it's easy enough using a SQL search ( SELECT guid, post_title FROM wp_posts WHERE post_content LIKE '%[shortcode_name%'; ) but it would be great to be able to do this from the MainWP Dashboard and maybe generate a client report for it.
