Can you duplicate and move objects in a sequence?

Can you explain how you added the additive track in this example? I’m not sure what I’m selecting to add that track. Is it something from this list?

Thanks!

edit: oh wait did you add the +section Additive directly to the object? So I would just do that for each object? Is there a way to add a transform that would apply to more than one object? or a folder of objects? Testing now…

edit2: I guess my concern is that I have 5 objects that I want to move and rotate as a group to keep the relative positions between them the same. If I move and rotate them individually their relative positions between each other won’t be the same anymore. ie: I want to rotate the entire animation spline and not the individual objects in local space. Location movements won’t be much of an issue but the rotations would be. (I think)
