Hi @J Kirk thank you so much for your patience. I spoke internally with the ACS engineering team and they confirmed that this can be done in principle. However, we need more details around your usecases, the countries where this is required, etc
Could you please send us an email to AzCommunity[at]Microsoft[dot]com with the below details, so we can connect you with the engineering team?
Email subject: <Attn - Grace >
Thread URL: <Microsoft Q&A Thread>
Subscription ID: <your Azure subscription id>
Please let me know here once the email is sent along with above requested details.
Thanks,
Grace
