Adding linked staff

Thank you for the new MS4! After downloading the 4.01 fix for the numpad note value control. I'm mroe than happy.

The v4 apparently does not allow for Linked Staff functionality - I need it especially for Classical Guitar Tablature. I cannot find anything in the manual that can assist - all refer to the v3 options, many of which are not (yet) available in v4.
Can anything be done about this?
