Text flow controls

This is a call for discussion. I often think it would be useful to have better control over how text is arranged in relation to measures and music.

For example, I am often struggling to correct tempo markings that stick out into the margins, such as the text "Cadenza" in the following example:

Would it be feasible to introduce some kind of text flow properties into all text objects? What kind of model would fit for MuseScore?

Lilypond has a command \textLengthOn (and \textLengthOff, respectively) that controls whether text and music may overlap. See this illustration from the lilypond manual:

That would solve some flow problems, maybe not all. Is there a MuseScore equivalent?
