Automatic addition of Full name as Display as in Contacts

I have a very large Contacts list. Some are entered by me directly, some are added through automation. However, for many of them, the “Display as” field is not populated. This results in the ugly email address being shown in the “To” line.

What is needed is a simple menu setting "Update “Display as” automatically. If TRUE, then if a “Display as” field is empty for an email address, emClient will automatically populate it from either of Full Name or Company in that order.
