Add Shout to NPC?

[kaleidx]

Is there a way to add a shout to an NPC with scripting? The only method on the wiki available says it corrupts saves, wondering if anyone found a way around this. I'd like an actor to learn shouts on certain conditions met, so adding them in the spell list is not an option.

 

I've tried equipshout but it doesn't work as intended.

I've tried adding conditions to MGEFS of the Shouts but the NPC ignores them.

AllowShoutingPerk is also ignored by NPCs and can shout without them.
