New Timeline With New Sprites

When I add a new Timeline to a scene, can I add new sprites/objects to this new Timeline that will not appear in the main Timeline? There should be a checkbox like “Show on all Timelines // Show only on this Timeline”.

You use the elements properties to hide or set the opacity in the timeline for the element at a given point (keyframe) and duration.

This may be a bit over complicated but I am trying to show a couple of ways to not show elements on different timelines.
