Payroll - Link Different Income Accounts

Hi. 

Using Sage 50 Premium Accounting (Canada)

I want to show the commission paid to our employees as a different account/income account.  I created a new one and linked it, but when I do up a pay cheque, the income is all out of the same account (boss wanted me to do this to make it easier to see how much was paid in commissions).  Is this possible?  Thanks.
