Overriding Birth Animation

So guys I am wondering would any of you be so kind to tell me how to create a building which uses triggered birth animation instead of its original birth animation. For Example Moon Well which uses Naga Birth animation instead of NightElf Birth animation.

Make your builder construct a naga building with the appropriate birth animation instead of moon well. Then check the "finishes construction" event. Replace the naga-building with a moon well when the naga-building finishes construction.

Themerion is right, but you have to make the Naga thing called a moonwell. You can just rename the coral bed or something. :P

Because you can still click the building when it is under construction, thus if you see "Coral bed" when in actuality, it is meant to be a moon well, it will bring a load of wtfs from the user.

Thank you guys, you both were very helpful, that was just the thing i was searching. Thanks a bunch very very smart idea.
