Possible to have empty staff fill rest of width?

I have a decorative use case where I want to be able to write a line with some notes, but at the end of the last measure the staff continues empty to fill the rest of the width of the parent?

If I understand you correctly, you should add this line to your string: %%stretchlast

You can also make the staff line shorter in general if that is what you are asking: %%staffwidth 400 where you can experiment with the number.
