Combine multiple contact types into single list for a Program

Hi Jessica
I think that an option would be to split your dataset and then union it

Dataset 1: All your fields
Transform A: Fetch from Dataset 1 Opportunity ID, Order Signer Name, Order Signer Email
Transform B: Fetch from Dataset 1Opportunity ID, Company Contact Name , Company Contact Email.

To make the next part easier, change the field display names to "Opportunity ID", "Name", and "Email" in both transforms. It'll get them to line up, and then you'll get an automatic union.

The Union of A and B will give you the desired output

Sorry I didn’t clarify before, this is using Data Designer as Audience source.
