Include Get Previous Value in Adobe default product

While I agree with you that this would be a nice feature, this isn’t so easy to make work the way you would like…

This feature uses Cookies to store the “page” value, then on the next page, read that value, put it into the dimension of your choice, then override the value in the cookie to be ready to track on the next page.

Cookies can be set to “.website.com” and work on both www. and secure. in your example… but for other uses, like moving between domains (on the same tracking suite/implementation) such as www.domainA.com and www.domainB.com are impossible, without sending the data in an alternate way (like appending the previous page name into the URL with a query string parameter… which may not be ideal for all companies.

I think this is why Adobe has a specialized panel in workspace for “Next or Previous” where they are using segmentation to get the previous value, without the need to track an extra value in a custom dimension. This will work across both sub-domains and fully different domains. 

You should check this out and see if it supports your needs.

I am still going to give you an upvote, because any tools or improvements for understanding our User Flows is important and even if this doesn’t get picked up exactly as requested, it hopefully will inspire improvements in this area.
