Tempo/Rehearsal Marking Section Placements

Probably not. This is information for the entire score, a kind of system text.
Can you explain why you need this?

These informations are transferred to each parts when you have created them. And you should do this if you want to print it out for the individual instruments.

There is, sort of, a way to have these system type elements getting repeated on another staff, but the way to do this is not available via the UI, it is embedded in some templates though

The code to insert into the .mscx file at the proper place (just before the 1st <Part> tag) is

    <SystemObjects>
      <Instance staffId="9" barNumbers="false"/>
      </SystemObjects>
 

The staffID of course needs to get adjusted too
(as you can see there's also the option to have the measure numbers repeated, no idea though whether that works)
