Content blocks limit tracking

Feature Request Summary: 

We should be able to track the usage of content blocks, including translations.

Description/Use Cases: 

The current "manage content blocks" menu displays the number of articles a content block is linked to, but this number does not account for translations. The workaround given by Zendesk Support was to count them manually by opening them one by one, since the left side menu flags the translations in use.

Business impact of limitation or missing feature:

For large knowledge bases, it is not sustainable to keep track of them manually. In my company, we have a content block that appears at the top of every article. This block helps users identify which solution the content belongs to, since our company offers multiple solutions. We wanted to use the same content blocks across all languages, but since there is a limit of 500, I am unable to track their usage across different languages. This makes it almost impossible for me to implement them in the translations.
