Geckolib model with minecraft basic humanoid animations.

-English
Hello everyone, I apologize for any errors as I am using a translator. 
Anyway, I'm making a mod that doesn't have complex animations, but I need to use a geckolib model because I want a model that certain limitations of Modded Entity (Java Models) don't allow. 
But I can't use the standard Minecraft animations (Model Biped / Humanoid) in this model because Geckolib requires you to import your own and as far as I know there is no way to use the MCreator standards in this model. 
So this would be the help I need: A model/animation file containing the standard minecraft animations to import into geckolib, or some way to do such a thing.
Thank you in advance!
