Hi @anthonylin & all - Thanks for following up! I assure you we’re aware of our customers’ pressing need for this functionality. We’re going to deliver this feature, and this is part of the team’s highest priority project at the moment - we’re actively working on it. We hope to deliver this soon. I will update this post as more specific information becomes available.
To follow up to @bmccluskey’s observation, this feature will be delivered as part of an overall/ongoing effort to create parity between company/deal/ticket/quote workflows and contact workflows. Contact workflows were built on our original workflows system, and the others have been built on a new, more performant workflows system. We’re actively working on moving contact workflows to that same new system, and as we make progress on this project you’ll see many positive benefits, such as this feature of copying deal/contact properties in both directions. Stay tuned for more details!
