"Edit multiple keyframes" and "selective onion skin" in cut-out animation

Hello! I’m using harmony for very short time and I have two questions about cut-out animation:

-Is there a way, in cut-out animation(with pegs), to move multiple selected keyframes on camera at the same time without create a peg for all of them?
Like the option for Adobe Animate “edit multiple keyframes”.

-About the onion skin, is there an option(still in cut-out animation) that make you see only a selected keyframe in the timeline, and not all the ones between?

Thanks a lot for your attention!

Select or Shift+Select multiple keyframes and drag them about.
Right-click any keyframe and select Set Ease for Multiple Parameters.
From the View menu select Onion Skin and choose your options.
