That's not confirmation. The funcionality of Weiss' gold glyph isn't clear, even assuming it does always have the same effect. There is no explanation for how Blake uses the attack, given it's not a function of her weapon or her semblance, and both times she's used it, she's either been empowered by Weiss' glyph or using dust to enhance her attacks.

Of course it's not perfectly safe to say that she can't do it on her own, but we have nowhere near the proper information to say that she can.
