User blog:Precurefans11/Cure Echo is a cure in Smile Precure?

So according to informations about Cure Echo that I have right now, seems that Echo is a Movie Exculsive Cure but also in Smile's group.

She transforms by using a White Cure Decor and have a symbol of Smile Pretty CSmile Pretty Cure on her sort of ribbon on her chest. SO IS SHE ONE OF SMILE'S GROUP AND WILL APPEAR IN THE SERIES SOON??
