Hi, what would be the best way to add conditional feature checks, lets say I have made new "sold out" options for products thats sold out, we want to run an experiment on this new feature and track if the new options are better, but we only want to check to see if the feature is on / off when the sold out criteria is meet. There are other parts besides the sold out part that changes depending on this feature due to structure of the code. We currently useFeatureIsOn, but can't seem to figure out how to make it conditional, which I assume wouldn't be possible with the hook, but maybe some other form of feature check that also fits the tracking part as we only want to track the viewed experiment if it actual hit the criteria.
