Cross Hotbar Question

[Mazzoutlaw]

Is there a way to have a crossbar show up using L2 > R2 or vice versa, but never when hitting R1? Basically, I want to only have bars 1 and 2 toggling with R1, and use bar 3 for items and rare occasion actions (never wanting to cycle to it using R1). I'm not sure if this is possible to set up, but looking for input anyway.
