Feral Druid / Action Bar

[marioinfinity]

So i realize the top action bar has 2 bars in it; and when you shapeshift it actually saves yet another bar. I was curious if it's at all possible to have it remember a 3rd bar? I've used barmods in the past where i can shapeshift; and my main bars change, but when i use Prowl in kitty form, it gives me yet another bar where i can put my prowl abilities on. So like changing forms, prowl would trigger another bar without having to auto switch bars or use another bar for those abilities.

Was just curious if this was going to be at all possible in nui6..
