on an orchestral score, the left end is obviously set according to the space the instrument names need.
When there are more then one systems on a page, each system starts on another left margin. When the instrumental names are short (Vl.) the system starts more to the left then with long names (Horn IV in F).
It look ridiculous, when the systems on one page are not aligned and each starts on another position.
How do I get an suitable alignment on the left side?
