Compare different segments of traffic

After we build the saved filters functionality (#199) it would be nice to expand the comparison feature to allow you to compare two segments of traffic against each other (cohort analysis).

Agree, current option seems to be filter > export > clear > new filter > new export > open both in Excel for comparisons – doable, but slightly annoying. Having on screen comparison of e.g. utm_campaign A vs utm_campaign B, similar to comparisons of today vs yesterday, would be awesome.

This would be very helpful to be able to track our content categories, and content by date (if there were a way to filter content by publish date or first discovered date we could see how our 2023 content is preforming as a whole etc…) Thanks!
