Change "Append '-converted' to filename" to something else

[Hello Paul]

Hello,
I'm currently working on a project where the client wants two versions of each video I'm producing - one with audio, and one mute. The quickest way to do this seems to be to export the videos with audio from Premiere Pro (that I'm using to edit the stuff), then do a conversion in VLC to strip out the audio (which it seems to do almost instantly, therefore I can assume there's no re-encoding going on, which is nice). The only pain is that instead of appending "-converted" to the filename, I'd like it to say "-mute". Currently I use Bulk Rename Utility to rename them, but it'd be easier if VLC would give them a custom filename. Is there a way to do this?

Thanks in advance for any help!
