Currently, in a journey, when I select the email to send to, I can only pick one for all segment members. For example, I want my newsletter to go to everyone's primary email, or I could select a different email field option like work email, etc. But I can only have one.

We would like a way for a contact or lead to say I prefer newsletters go to my work email. So I can choose in the journey my email is a topic for newsletter and then logic to look at what the preferred email is for each contact/email address. EXAMPLE: For contact A it goes to their primary email. For contact B it would go to their work email, because that is their preferred email address to receive newsletters at.
