Thanks, Smartrise got back to me. Here are my notes. I guess sometimes you just have to get the right guy on the phone.
To add hall call lockouts up to 4 landings:

Scroll to the available input
Set Group to Auto Operation
Set Parameter to HC Lockout A (1st Landing)
SAVE
Scroll to the next available input
Set Group to Auto Operation
Set Parameter to HC Lockout B (2nd Landing)
SAVE
Up to 4 landings A, B, C, D
MENU > DEBUG > ADJUST PARAMETERS
Set these parameters as necssary to enable lockouts
13-168 = x00 (1st Landing)
13-169 = x01 (2nd Landing)
