Audition problems with ASI5211 analog pair & AES stereo in at same time ...

Question

That is, the Audio Science ASI5211 card is advertised as essentially a 4 mono channel input card, 2 of which are analog and 2 are digital. However, I haven't been able to get Audition (CS5.5 or CS6) to recognize this capability. The ASIO/MME/WDM driver sets supplied by Audio Science (so far, versions 4.10.7 through 4.10.20) and its associated desktop driver control panel seem to show this ability as 2 separate stereo audio streams that can be set to pass either of the physical stereo input sources (Analog & AES). I select one stream as analog and the other as AES, but I can't seem to map these streams/inputs discretely inside Audition in the "Multitrack" view to 4 different channels.
If I use the ASIO driver class in Audition, I'm only shown a single "Default Input" stream (# 1) and can select among either the left or right physical input to map to the left or right stereo Audition channel. This appears to be the limit of my choices in the "Multitrack" input select view as well.
If I use the MME (WDM) driver class, I can select between the 2 streams (#1 and #2)  as "Default Input" but again, whichever "stream" is selected, that's the only choice I get in the "Multitrack" input select view ...
I also have another instance of Audition that is running on a pair of ASI5644 cards (4 stereo record streams per card) and the ASIO driver class, that I don't seem to have this kind of problem with.
The Audio Science drivers are a "monlithic" kinda deal in that the one package is intended for most (if not all) of their product.
Any ideas?

I hope this is at least somewhat clear.
Thanks in advance for your time and attention.

Steve,
Thanks for the response. I was able to get an answer about this from Audio Science and it appears that, like a number of things, this capability of deriving 4 discrete "mono" channels (2 Analog + 2 AES) from the ASI5211 card *WAS* possible in Audition v3 using Windows drivers, but it was amputated from subsequent versions of Audition.
What I was told was that the absence of this ability, using the current ASIO driver, is somehow due to the hardware architecture of the card. Not much more was revealed.
Nothing at all was removed from Audition's ability to pick up and send correctly formatted ASIO streams - otherwise just about every other user would have screamed from the rooftops, and it would have easily been picked up in beta testing.
Reading between the lines, I'd say that they were being 'economical' with the truth here. What it amounts to is that they've screwed up their ASIO driver - period.
