Special use case for Razuvious in Naxxramas

[zembtach]

Is it possible to have a special spell duration displayed for the taunt debuff on Instructor Razuvious from his mind controlled Deathknight Understudy?

It has a 20 second duration instead of the normal 3 second duration from player Taunt. It would be really useful. But I understand the difficulty when it just has the same name as the normal spell, and we're unable to see the spellId.

But again, it would be suuuuper nice. 😊

In DBM the spell cast is checked for sourceFlags in the combat event to see if it's a pet casting the spell. But it's obviously only active during the boss fight.
