Reporting on visitor page/url when chat strted

We are wanting to report on the page or url that a customer is on when requesting a chat to be able to get a view of the proportion of chats started on each page.

We are unable to do this and I was shared an article which provided a recipe for completing this, which advises that chat triggers will need to be created for each page/url to add a tag to the chat in order for this to be tag to then be reported on.

Our website has 10,000+ pages/urls and it is likely to be nearly impossible for us to have a chat trigger in place for each page to add a tag to identify this. Also I am unsure why this is not something the system can do as standard as in agent workspace the url is added to the ticket information on creation, so the system is recording this information.

There should be an attribute or metric available to report on the url or page the customer is on when joining the chat, so that the information seen on the visitors tab within the chat dashboard can be reported on. Why can we see this live but not report on this?
