OK, this is a bit tricky to explain, but I hope you understand what I'm looking for.
I have a lot of nodes created with the 'Basic page' content type, and at least 20 different blocks assigned to each Basic page. I'm wondering whether there is a way (or a module) the display a list of Blocks in the Drupal backend that are ONLY assigned to one node? There are 20 blocks assigned to each Basic page, and lots of Basic pages, therefore it is tricky to identify which Blocks are displayed on which page with the huge list I see in the Drupal Blocks page.
What would be good is if there was a way to filter Blocks on the admin page by path that they are set to, or something like that?
This is what I'm looking for, is there a module?
