Hello OpenAI I hope you are well. I am the AI engineer for a large media company. We currently use your API across several projects which all have different budgets and expense cards. One huge hinderance for us has been the inability to set a projects API keys to a specific card and api limit. Each of our projects is compartmentalized It would be extremely valueable to us if we could set specific billing cards to specific projects and set limits per project. thank you for your consideration in this and all the hard work you put into your product/service
