[cinder] revert volume to snapshot

Hi, There is a restful api[1] to revert volume to snapshot. But the description means we can only use this api to revert volume to its latest snapshot. Are some drivers limited to rolling back only to the latest snapshot? Or just nobody helps to improve the api to revert volume to any snapshots of the volume?
