Saving binaries low-byte-first

Hallo,

question is quite simple:
is there a way an binary in the old, DOS-like low-byte first format?

I try to fix some jitter-artefacts in some old binary data files.
For this I load the file with gBwaveload and the /B flag. After correction I would like to save it in the old binary format afterwards, but there is no GBwavesave /b (or similar).

Just SAVE uses the high-byte first binary format.

Thanks for any suggestion

Ralf
