I don't believe this currently exists.

I'd find great value in being able to add "tags" to urls to group them. Yes, if urls are constructed properly they should essentially do this, but there is still a need to be able to provide additional data via tags, so that you can view the performance of a group of similar pages (i.e. Ecommerce catalog pages, Ecommerce Product pages, Any other content strategies). I attached a screenshot of where I could see them going. There would obviously need to be more thought put into how you go about managing these tags, but I just exported all of my organic keyword list into google sheets & then added 2 columns of (tags/groupings) and then built myself a data studio report, to get a better view into what content groups are performing well and what groups are falling behind.

Love the product & love your willingness to listen to your customers!
