Custom Email Address ("friendly" email address) for Ideas Portal

It would be helpful and easier for user adoption of the Ideas Portal in our organization of over 1000 employees if we had a custom email address that could be used to submit ideas (or in our case, requests) to the portal.

In our organization, many users are accustomed to sending feedback or requests via email. Moving towards a Aha, as an organization, would be easier if we had a custom email that could be used to submit ideas.

E.g. It would be helpful to configure different portals with custom email addresses such as requests@companyname.com OR companyname@aha.io
