DtaExt folder in campaign-folder root. HELP

[Jahve]

I found out that there are sounds in a folder inside the RESISTANCE.pbo campaign at the path 'DtaExt\sound\'.
It is used in many missions. I want to know, if there is a way to use this folder to put music as I dont want to have to put the ogg files for the music in every single mission folder that uses it... HELP!
