integrate 2d blendspace dodgeroll into locomotion

I have used the 3rd person BP template for the foundation of my locomotion. I used a 2d blend space for this. It works.
I created a 4 direction 2d blend space for dodge rolls. I do not know how to blue print code this into the locomotion. I have completed all of the state machines and have them linked together in the animGraph. The sticking point is the blue print coding in the 3rd person BP. Any help would be appreciated. No I don’t want to use montages for the dodge rolls.
