Run animation withouth BlendSpace

Hi, i have several different walking and running animations and all of them use Root Motion, i want to randomize the use of each animation and use the Root motion of the animation, so i decided to create 2 AnimMontages (walk and run) each one with all of the walk and run animations in there separate in several sections, i know how to play the montage and jump to section, but what i dont know is how its supose to be the Animation Blueprint without any Blend Space in it
