there is a way, but its a little buggy
Viewing post in Sprunked Legacy Build Recreations comments
you go to the "when i receive loop 1/2" blocks, then you put a "animate" my block & then for the animate my block you put the code for the animation (though this will cause for when a loop is about to start, the animation will play but the time left for the loop to finish) its buggy but it works for me
