Snap Creator 3.6 can help. Although SC does not (yet) have Hyper-V plugin, starting with 3.6 release (available on NOW July 19th) you can have SC manage external snapshots, menaing those created from SM products.

# NTAP_USE_EXTERNAL_SNAPSHOT - (Y|N) Setting which allows for import of non Snap Creator snapshot, most recent #

# NTAP_EXTERNAL_SNAPSHOT_REGEX - A regular expression for matching imported snapshots, requires the #
