Morale and OpCode 23

Wondering if anyone has any insight on whether you can change an NPC's morale. It doesn't seem to work for me with a scripting action 103 MoraleInc(O:Target*,I:Morale*) or with OpCode 23 which should allow you to increase of decrease their morale.

It's possible the actions suffer from this limitation as well, only capable of those default values.
