Joining short lines together

If I put in a line of music which doesn’t fill the complete stave and there is a second line on another which I want to join up to the first, is there a way of doing this without rewriting the second line again in its new position?

@dave4fenton, you can resize each line with the handle on the right side (shown below)

Chris,
Thank you for your response. Sorry for the delay in replying.
