White listing a subscription for a staged image
With the new portal, one cannot whitelist a subscription to an already staged image.
Instead, one needs to bump the version of the image and stage again.
This was possible in the old portal and is highly needed.
This is a critical short-coming for us too. We also assumed (incorrectly as it turns out) that the publishing account did not have to be whitelisted. It also seems like without this feature it would require Microsoft to do more work since we need to cancel the publishing effort and restart it every time we change our whitelisted subscription IDs.
