When creating a new management scenario, you'll be given the option to copy management information from your current (baseline) management.
This feature can save you a lot of time if you are only changing one or two elements of your baseline management (i.e., switching from intensive to no tillage or adding a fertilizer application).
If you've already created a scenario but are making another, you will also be given the option to copy management information from another scenario. For instance, if you've already created a management scenario where you practice No Tillage, but now you want to create a scenario that practices no tillage AND implements a cover crop, you can copy information from your first No Till scenario.
This can again save you a great deal of time inputting all your management information from scratch.
