Raiden giant bomb

Is there a way to short cut light giant bomb into ex giant bomb

Dreamcancel says this:
-Canceling dp into dp (e.g Yuri’s dp+A, [DC] dp+K)–> dp+P, K: As long as the first motion is the same as the second motion and there’s not too much lapse in between, you can just press the button again.

If that doesn’t work, get good at charging, I guess.
