Precedence of notes

How does one set overlap priority? If you can not, this aught to be implemented somehow.
Here is a snippet from Claude Debussy's Prelude 1er Livre:

In an attempt to implement this into MuseScore I come across a problem having to do with the upper voice with the overlap:

A previous post of mine (https://musescore.org/en/node/110121) talked about making a blank text box over an element, but this then supersedes the notes as per:

Is there a way to either take that blank box and have it be set in the "background" but not completely in the background? e.g., the foreground of Voice-1 but the background of Voice-2 or something similar? or is there another method of doing this?

Any help is much appreciated :)
