AWS Budget at OU

I am looking to create budget at OU, I know it is possible to create a budget and add filter for the Linked Accounts but is it possible to create budget at the OU. The idea is to implement if the budget exceeds for the OU instead of the individual accounts https://aws.amazon.com/blogs/mt/manage-cost-overruns-part-1/ https://aws.amazon.com/blogs/mt/manage-cost-overruns-part-2/
