Sound files read from folder?

[Jagohu]

Is there any way to avoid having to put each sound file to play into the .miz file? Like can they be somehow located in the Saved Games folder and read from there?
This doesn't really work for me, I tried it many ways, but can't crack it - only if I do it from the ME and then the file gets included in the .miz file.

 

trigger.action.radioTransmission("Sounds/Speech/ENG/Common/test.ogg", trigger.misc.getZone("CVN71_TIMEHACK").point, radio.modulation.AM, true, test_freq_radio, 20, "ZONE")
