Modify Audio Channels - remove Clip 1 & 2 but keep other Clips?
In Modify > Audio Channels, I cannot find a way to remove Clips 1 & 2 but keep other clips (3, 4 etc). Unchecking the unwanted clips will cause that audio to not show up when playing the clip in the Source Monitor (so only Clips 3 & 4 will show up as audio in the source monitor), but when adding to a sequence, it will have 2 empty audio clips in Tracks 1 & 2. While unchecked, if I change the "Number of Audio Clips" to 2, the two that remain will be Clips 1 & 2.
Original:

Want to remove the ones in red:

If unchecked, unwanted audio will not show up in Source Monitor when load clip:

But will insert blank audio clips into sequence (in this case, the unwanted clips were blank, but inserts blank even if unchecked clip has audio):

With 2 Audio Clips, 1 & 2 always remain:
