Like system text, which attaches to the top staff of a score which then propagates to all parts, it'd be helpful to also have system images behaving that way. Proposed shortcut: Ctrl+Drag
(note though that attaching images to measure doesn't work in 3.4, see #292606: image attached to a measure doesn't show, so 3.5 is needed)
