Hello Growthbook team, I want to use user attributes which cause the visitor to see a specific variation of an experiment is this possible? If so How or is their another way to force visitors to a variation in an experiment.

Hi Rudger, I just replied to Pascal about this in the shared Slack channel. 😀 If I understand correctly, you should be able to add a Targeting Rule to the experiment that targets users with a specific ID. For example, the rule could target based on an attribute like ​`internal­_user­_id`​ (or similar) and you can specify which values of ​`internal­_user­_id`​ should be shown the variation. You could also look into Saved Groups if you need to target the same user(s) across Features or Experiments.

Is there a specific order to do this? First experiment rule and the the overrule rule?

Not that I'm aware of, no.
