How can I change the vector store expiration in my organization settings?

I received the email below informing me that I’ll be getting charged for active vector stores starting this month.

I want to set an expiration policy, but I’m not a developer, so I don’t know how to do that with code. Is there a way to do this on the Dashboard? Meaning here: https://platform.openai.com/storage/

I’m also hoping there’s a way in the Dashboard to bulk delete vector stores so I don’t have to do it one at a time. I have a lot of them it looks like.
