Domain Control - Multiple Domains, Same User

RedBaron Expensify Customer Posts: 2 Expensify Newcomer

I have multiple domains, which for the most part separate my users. I have a few employees that belong to multiple domains. Since we are using the credit card feed option based on the domain, how can I have 1 employee listed on multiple domains?

They do have an email address for each domain (ie: [email protected], [email protected])

Is there a way to say that [email protected] is the same person as [email protected]?
