I would like to run a report which tells me how many instances of our bespoke Grid blocks (app_plugins) have been used across the site and possibly a URL that tells you the actual pages.

For example - we have built a Quote block using the Grid Layout - I would now like to see how many pages it is on and where those pages are.

Is that possible to create or is there already a plugin that does this? Can it be done in God mode? We have God mode but I can't see if there is anything that does this.

Thanks
