Unsub provides a number of Parameters to let you customize a Scenario to your institution's environment and to experiment with different assumptions about the future.
Parameter values are stored as part of the scenario. Parameter values can be changed using the "Parameters" menu. You can make a new scenario that has the same parameter settings as a current scenario using "Scenario➞Make a copy".
