Print multiple messages in Mail, but only page 1 of each

I am using Mail in macOS Sierra and I'm going to describe a feature that used to work in versions prior to Mavericks, but since then appears to be gone. I contacted Apple's Feedback department many months ago explaining what's now missing, but they haven't added it back and my staff and I need it - it's a time-saving, paper-saving, ink-saving feature.

The feature that I'm looking for is the ability to highlight and then print multiple messages in Mail, BUT only the first page of each of those messages. My staff and I highlight multiple messages to print all at once, but we only need page 1 of each of those messages. Currently, if we highlight multiple messages we can print all pages of all of them, but not just page 1 of all of them. Instead it only prints the first page of the first message highlighted.

Does anyone know how to do it?
