It would be great if we had the ability to segment visitors based on multiple value evar/prop instances.
For example, I want to know how many of our users log into multiple accounts on our site, i.e. how many visitors are associated with multiple userIDs. Something like:
WHERE evar instances is > 1
evar values DO NOT MATCH
A workaround (although non-scalable) would be to create segments with multiple eVar combinations (Visit where eVarX=Y AND eVarX=Z). But I could see this as being very useful.
