Ah, figured out when playing with it more. So simple I feel stupid, lol.

Set it so that under "Customization when weapon is drawn" only bar 1 and 2 are checked off, then place bar 3 in the L2 > R2 and R2 > L2 category. This gives the desired effect. Funny, I could not figure it out for the life of me last night, but it only took 30 seconds today, lol.
