Is there a way to add custom workouts done - for the time period before custom workout was introduced?

I was wondering, If I could go back and add my custom workouts for the years 2020 to 2021. During this time, I have repeated FB-XT 7 times. This is a maintenance program and is scheduled three times a week. The other three days I have done workouts to learn handstand. I would like to get this data onto my workout calendar.
