It would be super-helpful to have a few ways to include the relevant recipients for an email, on a high-level in a group, to make announcements or send the same message to everyone at once. I know I can choose each individual person that I want it to go to, but if I can't remember off the top of my head all the names, I need to find a way to come up with a list, or have 2 windows open side-by-side, and open each individual trip so that I can remember which names to search for. It would be really helpful if there were options to: open a list of all travelers(or all with email addresses), and click checkboxes for those who should receive the message --- Select all --- Select all Primary
