Azure Bulk Credits (Production)

From the partner portal you assign a bulk credit to user, which then receives an email with an "Activate your sponsorship". Below it is says: "Important: When activating your sponsorship, you’ll be given the option to either create a new subscription, or to select the subscription you want to activate from a list of existing subscriptions. If you don’t see the subscription in this list, please open a support ticket.

To apply credit to an existing subscription, first verify and/or update your credit card payment information. When submitting your request in the Azure portal:

1. For Issue type, select “Subscription management.”
2. Select the specific subscription you want to apply credit to, and after the support plan auto-populates, select “Next.”
3. For Severity, select “C – Minimal impact.”
4. For Problem type, select “Switch to another offer.”
5. Provide any additional details and your contact information.

Azure Support will contact you to confirm your request before activating your sponsorship and applying your credit."

My previous experience (from 2024) is that the activation link did indeed give you this choice. I would like to know how Microsoft justifies claiming that these Azure credits are for "Production" use, to which I have the expectation that I can apply all of these benefits to my existing Azure production subscription, while Microsoft in fact makes it nearly impossible to do so. First it was made impossible to another credit to the same user more than once, and now it apparently made impossible to even assign the credits to an existing subscription.  What is possible, is it to create a new account/subscription for each credit and then move the resources from one subscription to another. We have 18 of these bulk credits. So we are expected to move our production resources to another Azure subscription 18 times a year? That is just insanity. Since we do apparently have the right to use these credits this way, way not give us the option to use these credits in a normal sensible way.
