how to shift complete composition incl. markers ?

[Eggu]

If I like to add some extra space to the start of a song (e.g. to add an intro),
I can mark all tracks and shift them to the right (in one step).

But is there also an easy way to shift all markers (e.g. used to mark chord changes) ?

It's on the wishlist.
