I have a Lumix S52 which always records 4 audio channels. I can modify each clip separately  by selecting the clip in the project panel and then selecting modify audio and re mapping the channels to show as one clip on the timeline. This works fine , however, although premiere allows me to select multiple clips in the project panel ,  It will not re map them all with one operation, so I have to do each one separately which is a real pain. Is this a bug?
