Selecting all the notes in a bookmark/timing change

[Brollyy]

There are situations where a whole section of the song repeats and copying the notes after mapping it once is a pain, since we have to drag-select and use mouse scroll to manually scroll through the whole section - it would be helpful to be able to select them all at once by clicking on a bookmark or timing change (dragging currently moves the bookmark/timing change, so maybe Ctrl+click to avoid issues?)
