On the calendar, instead of calling a workout " general", put the custom title that the trainer enters.
I have clients that hike, go to orange theory, ride their peloton, etc. I like to specify that for them on their calendar for the month so they can go into Trainerize and check it off. Instead, the calendar comes up with just an entry for General on every day even though I entered a custom title. I think they'd be more likely to open Trainerize and check off their workouts if the specific title was on the calendar.
