Thank you for your review! Having two schedules would be cumbersome! We suggest starting with your most recent year, the 2024 version, and then customizing your scheduler by substituting or adding the applicable items in each category. If the items you wish to substitute/add are a couple of years old, they may no longer show up as an option to auto-substitute. But you can always add them as custom items under the correct subjects; just click the Add Additional Item button! This allows you full flexibility under one schedule. If you need any assistance with this, please contact us at mailbag@timberdoodle.com!
Hope— for the Timberdoodle Team
