For Azure VM SQL log shipping, What is the reason for requiring storage account to be in the same resource group as SQL VM? Any workaround?

https://learn.microsoft.com/en-us/azure/azure-sql/virtual-machines/windows/log-shipping-configure?view=azuresql The prerequisite for log shipping in Azure VM based SQL servers is: > At least two domain-joined Azure virtual machines with SQL Server in > the same resource group as an Azure storage account for transaction > log backups. What is the reason for requiring the storage account to be in the same resource group as SQL vms? Is there any alternative if one or both VMs are in a different resource group compared to the storage account?
