Link Keyframes to Markers Is it possible to link Keyframes to Markers?

I'm at the point of creating more complicated animations and have created a number of Markers at key points in the timeline. It would seem logical to me to be able to link keyframes to markers so that moving a marker would automatically move the associated keyframes relative to the associated markers - for example, if one keyframe was 25% of the way between two associated markers then moving one of the marks could rescale the associated keyframes so that they remain at 25% of the way between the new positions of the markers. Is this possible?

I know I can select the keyframes in the dopesheet and move/scale them from there but moving markers and having them move/scale automatically would seem somehow more logical. Or is there a better way?
At this stage - no. A marker can be linked to a camera as a way to change the active camera during an animation but there is no link between markers and keyframes, it is not possible to move both markers and keyframes at the same time.

It would be possible to create an addon that would allow you to move markers and keyframes at the same time.
