I can help you track the charges for each location, carrieokie.

4. Checkmark Warn me when a transaction isn't assigned a class. 
5. Under Assign classes, choose the One to each row in transaction from the Assign classes dropdown.
6. Once done, hit Save, then Done.

After that, you can set up a class list for each account number.

Here's how:

1. Go to Settings ⚙ and select All Lists.
2. Select Classes.
3. Click New. Use the account number as a class name.
