I Want to know how to make the AI produce AI-only units.

These are essentially for units that require special player intervention to work(micro). These AI-only units are diferrent versions of certain units that are only made by AI so that AI can use them properly.

I've tried(these mean that it didn't work and the AI never made a single one of this unit):
-making the object prerequisite by a common warfactory and adding it to the attack waves.
-making an AI-only button and adding it to an impossible place in the commandset.
