Entering personal portion of labour expenses

If I am claiming labour expenses and a portion of the amount is for personal use, how should I enter the information in DT Max?

If a portion of the labour expenses was incurred for personal use, specify it with the keyword Exp%Claim found in the Labour-Costs subgroup. The entire amount will be reported on the labour cost form TP-1086.R.23.12, but only the business use portion will be deducted for business purposes on the relevant business or rental statement.
