Let's see the situations when you are setting those reminders -

1. In bed, all ready to fall asleep, you get up to get your notebook from your desk to add the reminder to your notebook.

2. Cooking with hands all messy, you wash your hands, dry them, go to your desk to add the reminder to your notebook.

3. Driving at 40mph, so you pull over in a parking lot, take out your notebook from your bag and add the reminder.

Yeah, I will take telling Google assistant to do this instead.
