Finding duplicate bodyfield content items.

Is there a way to search for duplicate content within buckets/snippets? There are instances where a snippet is shared between page A and page B but later they want to add a button to page A but not page B so a new bucket is created with the bucket content and the button.

Later they will ask for the button to be removed, at this point page A and page B buckets are displaying the same information but are using 2 separate buckets. This causes unnecessary duplication of the same information.

This practice has been going over in our site for the last several years. Now the size has become too big.

If this is possible it would help in cleaning up excessive content items and also help us to speed content updates.
