Use the API... it's called vAPI. You can set it to the number you want using the API. They are focusing first and foremost on developing and mainting the API, which is probably a daily chore with how fast things are changing for all the providers they're connecting together. I empathize with them having to deal with people wanting a perfect UI/frontend when they are literally targeting DEVELOPERS as their customer-base and are focusing on the backend. With that said, and as I've said before, more than once; they exercise poor version control, thus things break often. I have faith that they'll straighten things out. I have a feeling they're feeling overwhelmed at the moment.
