By being able to print what you see on the calendar with no changes being added.
Please do not include linked contact at the beginning of a template being used on calendar. What we put & see on the schedule should be what is printed. Also, it only adds the contact name at the beginning if there is just one. If multiple contacts are listed, nothing is put there, only making the printout more inconsistent. We add the client name to the subject line so that it appears on the schedule when we look at it. Otherwise you have to hover over each appointment during the day to see the name of the client coming in.
If people like this feature, then the contact name should appear on the calendar online. Not, just when printed. Thank you for considering this.
