More animation problems

I am following this tutorial:

From https://youtu.be/ogz-3r0EHKM?t=575 to https://youtu.be/ogz-3r0EHKM?t=721 if I want to add another animation, I would have to go in blender, make a new animation, reimport it to unity, and set all the animations up all over again which is is really annoying.

Is there a way to add a new animation to my character without having to redo the process from setting animations to making a controller?
