I have a group of 3 tags (DR_CREDIT_TIER_CHANGED, DR_PAYMENT_TERM_CHANGED, DR_DOWN_PAYMENT_CHANGED). The first time that one of those tags is fired in a session, I want the event to be event2. Any time that any of those tags are fired after the first time, I want the event field to be empty (see screenshot). Is this possible in Adobe Launch?
Since you're sending Custom Links, you can also remove the unneeded events from s.linkTrackEvents. So your s.events string can stay as-is, but your s.linkTrackEvents contains only those events that you really want to track with your Custom Links.
