Storage accounts firewalls currently allow white-listing of networks within the same region.

I have peered VNETs in other regions that require access to a Blob Store.

I am unable to add these VNETs to the white-list and when I try to white-list the address range I am unable to because it is only possible white-list public IPs.

This leaves no option other than to leave the firewall open to world access. Although it is possible to lock down access using IAM, the addition of a Firewall would be preferred.
