Ossia staff in piano scores

Piano scores frequently make use of a small staff above the regular score, to show individual, isolated measures showing realization of trills and other ornaments, suggesting alternate versions of a measure, etc. To do this in the current version of MuseScore is a fairly involved task. Hiding empty staves in the Style dialogue still leaves a visible staff on the system that includes the measure with notation. Hiding those measures involves measure-by-measure use of the Staff Properties dialog (to hide the system barline and make the staff small) and the Measure Properties dialog (to deselect Visible for that staff). And this still leaves one problem that seems unsolvable: the visible measure that is left has no barline at the beginning. You also have to be careful not to do the intuitive thing, which is to simply add a third staff to the piano part: this introduces problems with the brace and the barlines. There ought to be an easier way to do this and to keep that barline. (needed as well for organ and other keyboard scores.) Thanks for a great product!
