Yea, I was thinking more about something already with everything in it that I could practice like I do with my grammar schedule. Maybe it's not possible 😭
If you go to Resources -> Community Lists, you can search for "Keigo" or "敬語" , and it will display groups of words that have been made by other Renshuu users. You can add these to your schedules or make a new schedule with them. Hope this helps
