Not sure if this is Azure Functions specific, but it would be great to be able to specify a regex statement or a range of ports for a CORS rule for my function app.

My specific use case is I am working on a Twitch.tv extension, and the "developer rig" they provide for hosting the frontend files when developing locally uses a new random port number every time the files are reloaded, and I can't change that behavior. I would love to be able to specify a CORS rule like " http://localhost:[50000-60000] " but it seems this isn't allowed. I ended up just putting in a blanket "*" rule for now, but I would rather not do that long term.
