LAME Command Line Settings settings, everything, something, question, manual

john

Is there a way to manually set the LAME settings (command-line switches) when rendering to MP3? I have a set of options I like to use for various projects and the presets don't cover all the options I use. I've been using RazorLame, but I'd prefer to do everything in Reaper.

I've read the manual and scanned the forums (too many LAME hits to read everything), but I don't see my question addressed. Seems like this would be a common need. Am I missing something obvious?
