Autofill for longer url prefix

Feature request: Add new Autofill behavior option to "Fill on this exact url prefix".

The story: 

I need to login to a lot of different Microsoft Azure tenants as part of my work.

Most of the tenants use the same host login.microsoftonline.com followed by tenant id or name (e.g. login.microsoftonline.com/3b84bdc6-a81a-4f39-bbb4-b18b54fe06dc or login.microsoftonline.com/hkdev.onmicrosoft.com).

To make matters worse, most of the tenants also require TOTP, but each have their own TOTP seed and the 2FA pages are otherwise exactly the same.

So when I open the Azure portal for the first time each day, I'm greeted with the login screen to a "random" (basically the last used one) tenant and I don't now which one...

But Autofill only supports "Only fill on this exact host", which suggests all tenants at once and due to the obscure tenant IDs I never know which tenant I need to use.

It would be great if I could add the full tenant prefix url to the Autofill and it filtered by that :)
