Thanks Alex,

As can be seen in the screenshot after following your directions, I'm only seeing the ability to map to a single account. As the payroll setup allows me to add multiple custom reimbursement pay types, I was hoping to be able to assign each of these to the appropriate expense account. Is this not possible?

Edit: Scratch the above. I see you can do such a mapping via selecting "Each employee's wages are posted to different types of accounts (ex: salary, contractor, and so on)". If I make these mappings does this retroactively map them (i.e. past payroll) or only new payroll periods?
