I have received questions about the use of scope and creating new snapshots. Anytime you create a new snapshot, your scope parameters should remain the same. Once you have created the new snapshot, unless you clear those parameters, they will mimic whatever parameters were set on the last creates snapshot. Once created, you can then go in and adjust your new parameters. Just remember to save your changes for this new snapshot. Any adjustments you make, will carry over to your next new snapshot from there.
