There should be a way to link audio keyframes on sub-it tracks to the sequence

It would be great if the audio keyframes that are written to sub-it tracks during automation with an external sound mixer could be linked to the sequence in some way.
When the video sequence has to be extended or shortened after the mixing process, these keyframes slip backwards or forwards in the sequence and the sound mix of, for example, the sub-it track with a narrator is no longer correct. at the moment, the keyframes have to be moved awkwardly using the drawing pen tool, which is unrealistic under time pressure, e.g. for news reports.
it often happens that you produce a different version of a report, for example, where only a short passage is inserted or edited. and here it would simply be nice not always have to remix everything.
