Clef for 9 string Guitar

Hello djentlemen, I have a 9 string (in A0 standard) that i want to write notation for. What Clef would one use?

Its clunky to constantly switch between clefs because of the constant octave jumps in Thall music. I have been using piano grand staff, but is there a more efficient way to add a grand staff Guitar other than adding a Piano and switching the sound font?
