I understand why you feel this way, accounting500.

QuickBooks lets you set up multiple reimbursement accounts. But only one account can be selected on the payroll preferences. 

The workaround I can provide right now is to manually change the Reimbursement account each time you create a paycheck to an employee. That way, you'll have different accounts when tracking reimbursement transactions.

Here's how:

1. Go to Settings ⚙, then Payroll settings.
2. Click Edit ✎ next to Accounting. 
   
3. Select Edit ✎ to update a specific section.
4. Choose which account the transaction of the specific payroll item should go, then hit Continue.

I'm adding this article in case you need to change past transactions and determine what account type to use for payroll transactions: Change your accounting preferences in QuickBooks Online Payroll.

You may run the Transaction Detail by Account report to check employee reimbursements. That way, you'll know how much you still owe to them. 

Here's how: 

1. Go to Business overview and select Reports.
2. Find and open Transaction Detail by Account.
3. Click Customize.
4. From the General section, choose the range of your transaction from the Report period ▼ drop-down.
5. From the Rows/Columns section, click the Group By ▼ drop-down, then Employee.
   
6. In the Filter section, select the Distribution Account ▼ drop-down, then choose the Employee Reimbursement account.
7. Select the Employee ▼ drop-down, then choose your employee's name. 
8. If you want the report to show what you owe to all employees, leave this set to All.
   
9. Hit  Run report.

There are several payroll reports you can use to view useful information about your business and employees. This article will tell you about these and how to access them: Run payroll reports in QuickBooks Online Payroll.
