Way to decode specific channel(s) flac --decode?

Is there a way to decode user-specified channel(s) using the flac 
command-line utility?

I tried:

$ flac --decode --output-name=1.wav --channels=1 input.flac
ERROR: --channels not allowed with --decode
Type "flac" for a usage summary or "flac --help" for all options

It appears that using the --channels option is simply disallowed with 
--decode, or maybe I'm totally misusing --channels without realizing it 
(in which case I welcome correction).

Thanks for your help.
