I haven't heard of revert to snapshot task, but maybe you should check in the VCB groups for VCB script that might help you.
In development environments that I have created, I have used Netapp with FlexClone abilities, that allowed me to create the base environment and then take Netapp snapshots on this Vol and create new volumes which were the exact copy of the baseline Vol.
When I wanted to revert to more clean environment, I have reverted to the Netapp snapshot.
In that way you can remove the snapshot burden from your ESX servers.
