Blend Space Transition?

Hello, I have some blend spaces (crouch, defend, rifle jog) that I am wanting to add to my character to toggle on command. I know I can duplicate and reset to my characters skeleton (which is the same anyways). But how do I apply the blend spaces on toggle? (Edit current character animation blueprint?) Tried looking it up, but seems like there would be conflict with current set up and those tutorials. My character has the basic idle/walk/run and jumping in animation blueprint.
