Steering diodes or other forms of isolation are generally used when 
paralleling PS outputs.  I would first look to the manufacturer's 
recommendation for strapping.  Absent any data, you'll need to analyze the 
output circit in the context of sensing.  Then, apply the isolation diodes 
(e.g., high-current, Schottky types), taking into account the voltage drop 
across the diode.  With adequate isolation, it should be possible to use the 
sense lines without affecting the other output circuits.
