Snapshots manually created via a command line script aren't synced with SnapVault

On our source cluster, we have a volume that does not have a snapshot policy associated with it, as we are manually creating the snapshots from a command line (they are named hourly.20171218.09 as an example).


We created a SnapVault policy with our other cluster, but none of the manually created snapshots are synced and the "Policy Details" section of OnCOmmand manager shows the label as "hourly" but it says "Source does not have any schedules with this label".


Is there a way to SnapVault snapshots that are manually created or is the only way to have the snapshots created via a snapshot policy?
