The best way I can think of is:
Well first back up jdski's commandresponses.txt
1: browse to ..\Enigma\VoiicePacks\
2: make 2 new folders "jdski" & "davidwww"
3: copy all jdski's wavs to "jdski" and all david's to "davidwww"
4: open jdski's command....txt in notepad and change all the paths to match the new location.
5: open david's txt file in a new notepad and copy all his US settings to jdski's txt file overwriting the default USN TR/VS
6: close the notepad with david's txt file
7: edit all the path in the USN section in jdski's txt file to match the new location of the wav files (like you did in #4 above).
Its a bit of work, but i cant think of other ways..
Maybe TAG will in the next patch make it so each faction has it own txt file
