Feature Request: Please make Private DNS Zone for private endpoint in storage account truly customizable

Question

My company has a Hub-Spoke-Architecture with a central Private DNS Zone private.azure.mycompany.com defined in our Resource Group "rg-hub". Per tutorials by, e.g., John Savill (https://www.youtube.com/watch?v=K8ePZdLfU7M), I assumed this would be best practice for the following reason.
As a customer, I do not want several DNS Zones for individual PaaS-Resources / PaaS-Types, I'd like to have one single common DNS zone for ALL my cloud infrastructure and connect to machines via resourcename.private.azure.mycompany.com. This also simplifies conditional DNS forwarding.

However, when I try to create a storage account in Resource Group "rg-spoke" using the Azure Portal UI, I cannot choose my Private DNS Zone private.azure.mycompany.com.
The answer to this question says that this is by design, and that the only Private DNS Zone possible for storage account is privatelink.file.core.windows.net. This I find highly unsatisfactory.

Could you please make make the Private DNS Zone for storage account customizable? I want to use the same DNS zone as for my other resources.
