Color Notation

Hello,

I am a public school music teacher and I would like to start making worksheets for my students on Musescore. I know that there are some options to add color to scores by going to the Inspector tool, but so far I can only change the colors of notes or rests (or similar elements). Is there a way to change the color of a particular line or space on the staff? For example, if I wanted to highlight the bottom line (and make it blue) on the staff for students to use as a visual reference as they read.

If not, is there something similar I could do? I think this would be a good feature to include if it's possible.

Thank you
