Detect Level of Buff

[tml616]

Is there a way for a trigger to get the level of a buff on a unit (as an integer I would assume)? For example, if a hero casts Storm Bolt on a unit, the stun buff tooltip will show the level of the Stun (even if all the levels of Storm Bolt have the same stun, the level will be different).

Non-hero unit buffs do not show levels.
