A setting to prevent automatically adding exposures when sliding a drawing?

This is a bothersome feature and I want to know if there is a way to stop this action from happening;
For example, I’ve produced a segment of 10 key drawings that I now want to spread out along the timeline to see how the timing feels when I play them.

When I highlight drawing 2 through 10 and slide those drawings further down the timeline, drawing 1 now has 9 additional exposures after it.
Is there a way to prevent this behavior so that when I slide drawings, it doesn’t produce a bunch of additional exposures of the previous drawing?
