Hi group, What is the best way to able to use event targeting from GB side? To start experiment on a certain event basically.

we suggest doing bucketing before that event - then using that event as an activation metric for the experiment

I was asking because I wanted to start another test that I wanted to start only on a certain event not to impact another test that was started earlier. Since namespace can be only used with resetting the test it is sometimes hard when you need another test started in the same area but do not want to re-start the phase and basically are mid-journey with another test.

I understand. Setting a custom attribute for those users would work - you would have to store it yourself.
