Unit/Subject planning

I would like to be able to extract my lessons for a unit or subject I did during the year and have them “stored” for the future. For example, I’m teaching a unit on handwriting and might have 26 lessons and I can insert it into my lesson plan calendar. I might be teaching about bees and have each day planned in a unit and I can insert it in my calendar. However, there might be a year I do butterflies rather than bees and then I could insert that unit instead. Right now, I don’t want to copy my whole planbook from a year exactly the way it was done the previous year. We have a new math curriculum this year. So I don’t want mine from last year. Thank you!
