When I use the default mouse modifier left mouse drag while pressing CTRL+ALT over a take I can isolate a mono or stereo take but not a multi-channel take. The isolation process should respect the channel count of the source take. In the following licecap the isolated take is only stereo, thus only the first two channels of the original take. Instead it is expected to be 6-channel. I couldn't find another mouse modifier to get the multi-channel take isolated.
