Azure attribute mapping for provisioner (secondary email)

We are currently using our SSO to login into Freshservice. The SSO is tied to our UPN which is a number ID@university associated with the user as an alias email address. The problem is when they are replying to a ticket the reply is with their public email which is technically the secondary email. Is there a way in Azure App auto provisioner to add the Freshservice Attribute “secondary email” and have it assigned to Azure AD attribute? Below is the pictures of what we currently have configured and what our target attribute we can select are.

Howdy, I don’t know if he was entirely succesful. But [kovergard] in this post was aiming for the exact same thing.
