Indenting staves

Is it possible to indent a single stave on a page with one part? If so, how is that done?
If, for example, there is a D.S. al Coda I like to insert a line break after that bar and if there are only maybe two bars in that line I would like that line to be indented, as opposed to having those two bars stretching across the width of the page.
