Right now, the only field option to use the owner's name (in an email template to send them owner statements) includes their full name: first and last. When have we started an email with Hi FirstName LastName? Never. 😉 Please provide the option to enter owner's first and last names separately so they can be used individually as a field as needed.
This has been released! First and Last Name fields added on Owner, and new field codes to accompany. Enjoy!
