Writing out a progression in all keys is a good exercise in itself.
Be sure to check out the practice setting (gradation hat icon).
It will automatically shift/transpose your chart (or looped section) up or down the interval you choose each cycle.
You can write just one short sequence and automatically step up or down through all 12 keys.
Remember to turn practice mode OFF when done using it.
