Can I type in a frame number to expand to?

Hi,

I feel like this is a silly question. I may butcher the proper terminology. I apologize.

If I am on the timeline and my image asset goes from frame 1 -20. But I add new frames to 40. Then I grab the end of the image asset at 20 and pull it open to 40.

Is there a way of doing this so I can select the asset on the timeline and then type in somewhere what frame I want it to extend to?

I hope that made sense.

Thank you.
