Basically, we'd like to do something similar to the alias feature in Mixpanel where object IDs can be linked together. We have users who have an ID already set (we'll call it "analytics_id"). We use that in the Actor Property field when building funnels in Keen. We want to be able to link events that occur anonymously to those users with an ID set in a cookie. Is there any way to link 2 IDs together so that we can create funnels including these "anonymous events?
