RTTY and Split Operation

I am posting this again but to the proper Topic. I would like to know how others are using SmartSDR with DX RTTY operating split and RTTY contesting. On the 5000 I used two channel MixW. I copy the DX station on the left stereo audio channel and use the right audio channel to search and transmit. This enabled me to see the copy of the current worked station and place my TX on the same freq. This doesn't work on SmartSDR because it doesn't separate left and right channel. Even if it did, it wouldn't work because I can't assign multiple slices to the same DAX channel. My only solution that might work is to run two copies of MixW (1 channel), each on a different slice/DAX channel. The problem is that this will cause problems with MixW and its contest logging features. Does anybody have a better solution???
