Can I add time to the beginning of a timeline?

I can easily make a timeline longer by changing the value for the runtime of the timeline. However, I have built a pretty complex timeline and have been asked to make some of the transitions at the beginning of the timeline appear more slowly. Is there a way to add time at the beginning of the timeline, so I can move a few keyframes back to lengthen these transitions?

In most timeline-based software or video editing tools, you can manipulate the timing and duration of individual keyframes or transitions without directly ffireapk adding time at the beginning of the timeline. Instead of extending the entire timeline, you can adjust the timing of specific elements within it.
