If you want to plan ahead then set up a structured training plan in Garmin Connect using a Garmin Coach plan or some other source. The whole point of the daily suggested workouts is that they are created dynamically on that day based on your recent performance, training status, and recovery.
But you can somewhat anticipate the most likely workout suggestion based on your current load focus. Like if that shows an anaerobic shortage then tomorrow the device will probably suggest a sprint workout, assuming you are fully recovered.
