Multiple Device Types

Just wondering why we can’t select different device types for audio input and output… I’d like to be able to use Directsound for output, and ASIO for input, as I’m using asio4all to reduce latency on input, and it steals my crappy sound card’s focus so other applications can’t use it. If I could chose directsound for output, however, I wouldn’t really have an issue, as the only application I’d be inputting into would be Renoise.
