Stretch Keyframes in Sequencer?

In the Matinee there was an option to Stretch Section or Stretch selected keyframes where you could set a new time difference between keys. It also shifted the following keyframes so the rest of the animation would be unaffected.

In the sequencer I’ve only managed to find the Transform Selection option which scales the keyframes, but doesn’t shift the keyframes for the rest of the animation. This means every time I do this I have to move all of the following keys to make the animation work again.

Is there a way of replicating the Matinee method in Sequencer or has it not been implemented?

Any help is appreciated, thanks
