For Regulatory Labelling, we miss functionality of being able to un-merge tracked segments.

Currently, it is possible to merge tracked segments, but not to split them back to their original segmentation. Linguists sometimes merge segments even though they are instructed not to. This causes significant leverage losses when using "Keep initial segment origin and status" at perfect matching: if linguists merge tracked segments in what later becomes reference file, we cannot un-merge them there, but then the new source segments without a merge for such segments, and we lose leverage on such segments (and also sometimes segments around them, depending on file complexity/repetitions in content).

If we are able to merge, we should be able to split.
