T4 slips-2 types of taxable benefits box 36, and box 40

Trying to do these T4 slips correctly. Problem is sme employees have two different taxable benefits codes! They have box 40 (medical) taxable benefits and box 36 (low interest loans). I entered both amounts in the benefits while doing the paycheques, however there doesn't seem to be anyway to separate these two amounts! Is there a solution for this? I tried calling Sage but was on hold for so long I just gave up.
