[Openstack] cinder volume revert to snapshot

OpenStack community,

I am curious to know if there is a means to revert an attached volume to a
snapshot taken of the volume?

Where,

nova instance has two volumes, one root volume (dev/sda) and a data volume
(dev/sdb). Without destroying the instance to mount a restored volume from
snapshot, I'm curious if there is any means to simply revert to the
snapshot for the volume, thus eliminating the need to respawn a new nova
instance and attach the recovered volumes.

Thanks,

L
