Compose in treble and bass at the same time in piano mode

So I'm trying to compose with the pop up piano for certain reasons and I was wondering if there was a way to quickly switch which clef you want to compose in without having to actually click the staff with that clef? Like a hotkey that if you hold down it will go to bass clef instead because currently I have to manually switch between treble and bass and it's kind of a pain because it places a note down and I have to then remove it.
