It'd be helpful to be able to move clip markers to other clips in the same sequence (at the same timecode within the sequence), or to turn them into sequence markers, and vice versa. Between an editor and an Assistant Editor (AE), it is common for the AE to need to move markers the editor added to a clip or sequence to another clip/video track, or move sequence markers to clips, etc.
There was a post about this in 2019:

Also, is it possible to export sequence markers?
