Possible To Mute or Delete the Snare In a Loop with Drum Replacer?

Found a little time to play with drum replacer tonight, and have a question.  Is it possible to mute the sounds that you want to replace in a loop?  Admittedly, I haven't taken the time to read up much on drum replacer, but I've watched a few videos, and it looks pretty straight forward.   What i want to do is replace the snare in one of my loops with another snare.  I'm not trying to layer or blend the two snares,  just mute the original snare and replace it with another sample.  Is this possible?

To elaborate on that... no, unfortunately it isn't. 
 
If I'm understanding your question, you want to take your track, detect all snare hits, and then completely replace the regions of audio with a new snare so that no trace of the original exists (while leaving the rest of the audio intact.)
 
Theoretically this is possible, but in practice it's kind of difficult outside of the most basic cases. In a pure drum track (or even better a pure snare track), yes we could just mute the original audio while our sample gets rendered, but for any sort of mixed track it would sound kind of strange to mute everything while the replaced snare sample plays. 
 
Perhaps there are some sophisticated DSP techniques to do this, but the problem is certainly nontrivial. I know this is kind of ridiculous, since the name of the thing is "Drum Replacer", but unfortunately all you've got is layering/blending or rendering to a new track altogether. 
 
With that said, if the track is clean enough maybe you could render the replaced track as a new audio track, and then use your mixing expertise to "turn down" the original audio when your replaced sample plays in such a way that it sounds nice. To be honest I'm lacking in mixing expertise myself, but maybe someone on these forums knows the tools you could use to achieve something like this. 
 
Does that answer your questions? And does anyone know how this user could mix this new snare into his original track? I'm curious to know myself. 

I hear you. Since Drum Replacer is included with Platinum and therefore a feature aimed at experienced users, I think the thinking was that the user would want to handle this DSP on their own rather than rely on us to do it. Personally I think it would be a nice feature, but I can see a scenario where our algorithm isn't up to the user's standards, which would lead to them having to do their own fiddling on top of whatever we've done to the signal. Not that that would be the worst thing in the world, but I suppose people want to work with their audio rather then our processed audio when doing this high fidelity kind of work. 
 
I think Drum Replacer (Drum Replacement) is the generic term for this kind of technology, i.e Drumagog, DRT, etc.

so that's the name we chose. Our lead dev came up with Hit Factory, which I thought sounded pretty cool...
