So, we've just recently applied serverless budget polices to some of our vector searches and apps. 
At the moment they're all going to azure under one general tag that we created.

However, we needed more definition. So i added the serverless budget policies. I can see my tags in the billing.usage table.
However, these don't seem to be feeding up to azure? Is there a way to do that? Are they appearing under something else? How can i find them?
I'm currently exporting the costs from azure and reporting from that. 

Cheers.
