Individual stave margins

Just wondering if there's a way to adjust the left and right margins of staves individually rather than globally. This could be very useful in certain layouts, for example if you want to divide a page into sections, some of which need not span the entire page; or to create a book with musical examples. If I remember rightly, I think this is something that can be done in Finale, but Musescore doesn't appear to have 'handles' on the staves that you can move individually.
