In LEAP Bridge Concrete can you consider bonded prestressing strands as “Reinforcement” when determining allowable tension stresses in a precast concrete beam?

I am using AASHTO LRFD and IDOT does not have conventional longitudinal reinforcing in their PPC IL-Beams, but IDOT does consider bonded prestressing strands as sufficient in resisting the temporary tensile forces in prestressed concrete before losses. How can I make LEAP Bridge Concrete limit the beam top release tension stresses to 0.24*SQRT(f'ci) instead of 200 psi in consideration of the bonded strands?
