I might be missing something obvious with the new Management Portal for Windows Azure, but how do I select the subscription where the new resource (compute, storage, site, ...) is being created? Can someone pinpoint where the subscription selection takes place in the UI?
When creating a VM the first step(midway down the pane) has a section for choosing which subscription to deploy against. See picture for location:
You specify the subscription on the last panel.
New -> Data Service -> Storage -> Quick Create -> Url/Region/Subscription
