PS3 - use a macro to toggle between hotbars?

[Seoulstar]

enable R2+L2 , L2+R2 key combo on settings. it helps a loooot on my smn hotbar

There really is a setting for that?

I have 2 hotbars and I have L2+R2/R2+L2 enabled, I need to put less-used commands onto a third hotbar. In fact, in my post I twice said "third hotbar." :/

Thanks though.
