After reading through some of the posts they seem to indicate that it's possible to have separate expense accounts for EI & CPP for different groups of employees although only in premium version or higher.  

I have a client that has 3 locations and wants to separate out payroll expenses for each but not sure how to do that.  I created new accounts and set their category as payroll expense.  However when I try the link payroll accounts I don't see anywhere I can link the new accounts.  it just shows the default ones.    I don't need the payable separated out....just the expenses.  How can I link those new accounts and how do I indicate on the employee record to record their tax expenses to those new accounts?
