Storage limit & server location

hi!

I’m using Vercel Blob for storing files and it works perfectly!
But I’m afraid of users suddenly uploads a lot of files - so I want to enforce a storage limit. I already have setup a Cron job for it - but I’d also like to set a limit in the Blob Settings if possible. Can I do this?

Also, the storage is located on an american server and I need to switch to a european location. Is that possible? I can see it here but not change it.
