Allow Mirrored Columns in boards to be used in automations (Email addresses specifically)

It would be amazing to have the ability to use mirrored email columns in a board in automations. This way we can have one board with contact details for a client or employee and mirror it to other boards. This way the automation can live on other boards as needed and use that mirrored column. I have sooooo many use cases for this. Please VOTE! haha
