Playing animation after one animation depending on key (I need help or at least an information)

Hey, I don't even know if this is an option. Can I create with geckolib animations after one certain clicked on a key. Like my concept is making a revolver that on for example keybind press "K", will play animation, and then after it, you will be able to chose sort of action depending on key pressed. 

e.g: Player presses "K" button -> one animation -> only after that animation when Player presses eighter ("I", "O", "P") button, different animation is being played. 

If someone knows the answear, please reply :D

Happy new year!
