Has anyone convinced their broker to allow them to do this (make contributions to a conversion Roth IRA)? If so, what broker?

I'm almost ready to give up on Waterhouse. In April they told me it was illegal! In August they told me "very soon, probably September". Now they're telling me that it isn't currently possible and they don't know when it will be possible.

Perhaps I'd have more luck if I could point to a few other brokers that *do* allow mixing contribution and conversion Roths. And threaten to switch...
