Thank you for joining the thread, @millerdq.
I'd be glad to help set a budget amount per class across all accounts.
The steps provided by my colleague above is correct in setting up a budget by class. However, to create a budget per class across all accounts, you'll need to enter the budget amount by class in the Accounts section.
Then, please repeat steps 4 and 5 for the rest of your class.
