Hmm, with sweep it turns out to pretty complex actually.  Turns out it
lacks the ability to edit individual channels.  It boasts its
multichannel abilities, but they are of questionable utility if you
can't edit individual channels :-(  Audacity should be easier for this
stuff.

Anyway, there is nothing impossible, here is a hack:

* Assume you opened a stereo file.

* Separate the channels:

  + Sample -> Duplicate

  + In the first copy:

    - Sample -> Channels -> Remove Right Channel

    - Edit the left channel here if you wish

    - Sample -> Channels -> Add/Remove channels: select Stereo

  + In the second copy:

    - Sample -> Channels -> Remove Left Channel

    - Edit the right channel here if you wish

    - Sample -> Channels -> Add/Remove channels: select Stereo

    - Sample -> Channels -> Swap left/right

* Recombine the channels:

  + In one copy:

    - Select -> All (Ctrl-A)

    - Edit -> Copy (Ctrl-C)

  + In another copy:

    - Playback -> Transport -> Go to start of file (Ctrl-Home)

    - Edit -> Copy: Mix (Ctrl-M)

      Here you can control the volumes at which both channels will be
      mixed.

Audacity is really simpler for this :-) (from the track's menu
(the dropdown near the X) split the track, edit individually, select
both tracks with shift, merge the tracks back).
