[Koha] Overdue notices

Is it correct to assume that Overdue notices are only sent to Home email addresses (borrowers.email)? Some patrons provide both a home & a work email (borrowers.emailpro). Ideally, the Patron DB would be setup to allow staff to specify the default email address to be used for notices. Otherwise, Koha should send notices to any available address (work if no home address available, & vice versa.) At present, I believe we would have to copy work addresses into empty home address fields to ensure that Notices are sent out. Thank you, Cab Vinton, Director Sanbornton Public Library Sanbornton, NH
