Having cohort-inside-cohort will be a nice feature to have

Hi star, thanks for the feedback, Can you explain a bit more what you mean specifically?

Let's say First filter 100% users on basis of Attribute1 and get 50% of users, Now on those 50% users we segregate based on Attribute2 and get further split to test on

ok

in feature /ab test assignment

So you want to cohort users who got variation A in one test, and then create a new test just with that cohort? Do I understand that correctly?

yes you can say that
