Phenoix Egg

Can you use the model for a unit. The only choice in the editor is phenoix egg/phenoix but when placed into the terrain it is the phenoix and not the egg. So is there a way to use the egg without the bird?

Base the unit from the phoenix egg, and change the abilities, stats , stuff..

Thats what i did but when i place it into the editor it is the pheniox instead.

But test it in game.
