In a previous question I posed to the community, I was able to get confirmation that when a Target is Converted and merged with an existing Contact the system does NOT overwrite existing values on the Contact record. (https://help.zoho.com/portal/en/community/topic/campaign-associated-to-converted-lead)

I'm wondering if anyone has had any success in implementing deluge code, etc. that would force the system to update any/all fields when converting a Target and merging it with an existing Contact record?
