When an MQL has been synced to CRM, a real-time alert gets sent to a country marketing manager. He/she will often need to re-assign this to a regional marketing manager. Therefore, I need to trigger off of this change in lead assignment to re-send the alert to the new lead owner. But I'm not finding any of the Marketo fields (lead owner first, lead owner last, lead owner email, etc.) as an option in the "Data Value Changes" trigger. How can I accomplish this?
