Is there a way to clone an email template, thus copying all the To/From/Subject, etc. info? I don't see this addressed anywhere.
There isn't currently, but that's something we're working on in big overhaul to System Messages and Email Templates that is actively in development as I write this.
fingers crossed that the big overhaul will include the ability to have scheduled email reports. Most important to me would be a weekly automated email listing the checkin/out and duration for all upcoming bookings.
