						At the end of the top staff add an extra final bar line (i.e. system close, master repeat close) and force system close. Also extend last system in page setup. This will evenly spread out the measures in the last system. If there are not enough measures to be visually satisfying, force system close earlier in the piece so that more measures are in the final line.
