I would love to be able to do both.
You are suffering from an erroneous decision of ALSA team when it was changed a feature of the PCM API (0.4 to 0.5 transition): file descriptors were bounded up with channels, now is bounded up with cards. Separate operation on multichannel card is easy at application level. However, low-level operations (i.e. routing) for each channel at kernel level is unnecessary complex.
