Variable cage in columns


I design CIDH caissons for earth retention design. The caissons support walls and are subject to bending in one direction. I want to be able to mode the CIDH as a RC circular column and be able to have different reinforcement on the tension side of the column than on the compression side so make the cage as efficient as possible for the unidirectional bending. Can that feature be added to the RC design section of the program?
