Hopefully that's in the pipeline, I did a little workaround today, I have a track template for replacing drums, it's session drummer 3 with a midi kick track, kick audio track, midi snare track and snare audio track, I inserted a snare I wanted into SD3 and drew a midi hit on the snare midi track. I then bounced this to track so I had the audio clip, I then was able to place this audio clip in Drum Replacer. A very convoluted way of doing things but it worked.
