Each time you create a scenario, all source information added is copied from the Common Sources to the Scenario file.
Note: Making changes to the Common Sources DOES NOT affect the sources information in any existing Scenario file.
This allows you to create a multitude of different combinations between video and audio sources without extending the list of Common Sources endlessly.
To make use use of adjustments made in Common Sources, you can simply re-create a Scenario from scratch and replace the existing scenario file when you save the Scenario.
If you have rather complex Scenarios, making the adjustment to a single source again, inside the existing Scenario might be easier.
Some changes can be made without even opening the scenario, other require loading the scenario completely.
