Display name and text fields to be available for email signatures

We have multiple different email signatures that we have in place, but we are changing to Inky for signature management. The issue is we use Display name for all emails as the proper name is not always what needs to reflect on the email signature. We also have custom text that needs to be added, for instance our Ph.D. emails. Using licenses will not work as it is only approved for Ph.D., so the use of a text field is necessary. This is also needed for our vendor email signature, and for the shared folder from the President’s office. Without the ability to add text to specified email signatures the transition would take away from the user and recipient experience.
