Adding Origin Effect to Resitant Skin

[Huntsman]

In my map i have given all my demi Hero's a spell called AADemi Hero, which is based of Resistint skin (so they cant be charmed). But now i was thinking to add the Hidden Effect- Orc Command aura target to the spell, so people can notice which unit is a Demi Hero, Somebody know how?

+rep if helped.

Are the demi heroes premade or are they build?
Because then you can add the effect with triggers.
