Circular reinforcement pattern on Square Column

Hi 

I am looking to design a square column on a drilled shaft/Caisson however the square column size is larger than the caisson and would like to introduce a circular longitudinal reinforcement pattern in the column, so it sits well into the drilled shaft along with sacrificial reinforcement for the square column on the sides. I want to do that since I have seismic concerns demand. I wanted to know if that is possible in LEAP/RC Pier.  please suggest.
