Two staves on the same line

Hello,

I want to put two staves on the same line, but I can't succed in finding this option in musescore. I've done it with lilypond, but coding lilypond score is really harder than using mscore, so if I could find this option in musescore, il will be really helpfull !

PS: I'm not sure to post in the right section :-/

Here is the lilypond code I've done to obtain two staves on the same line, if it can help...

\version "2.13.18"
\include "english.ly"

\header {
title = "Musique Modale"
% remove default footer
tagline = ##f
}

\paper {
#(set-paper-size "a4")
}
