Monk Haris - order question

If you have got 2 shaolin monks and Liang Kai haris, I’ve seen mention of him converting the irregular orders to regular, but can’t seem to find this in the skills/rules any where for N4??

(sorry newbie player, in-fact first game yesterday) I know they loose the Impetuous and can’t use the Irregular orders with out splitting, so currently looks like I have 3 troops and no orders from them.

Many thanks in advance

 

Ah thank you so very much, what a muppet I am, forget to check that chart 0_o appreciate the reply.
