What-If / Sandbox Scenarios?

All,

New to OneStream but familiar with other tools in the space.  One request recently from a user was for a functionality similar to that of the "Personal Sandbox" capability within IBM TM1 / Planning Analytics.  This functionality allowed a user to easily create a new scenario that allowed them to perform what-if analysis and once complete, discard the scenario or (permissions permitting) push the new data back into an existing scenario.

Any functionality or approaches like this available in OneStream?

Thanks!
