An esoteric function of the campaign builder is the ability to save different campaign model configurations. This can be helpful when reusing common elements of a campaign but other elements change. For example, seasonal promotions or a product launch.
It is also helpful when innovating and improving an existing model. It allows us to safely make changes to the model that can be rolled back if necessary.
