notate a shortened chord?

Hi there,
I would like to write the chords for my song, but I can't manage to notate a shortened chord, i.e. a chord without a root note, for Musescore 4. Normally you would write "D7" there, for example, and then draw a slash through the D. But that's not possible. "D7omit1" would also be a way.
Greetings Lars

P.S.: I don't want to simply add a line by hand. It should also be played and be audible that the root note is not played.
