Finale  v 25.5 WIN 10.

I recently bought Sultans of Swing for 2 guitars and guitar tab.The two guitars are written in the treble clef. and use the standard noteheads,

except that some of the noteheads are as small crosses ( actually more like a multiplication sign) I seem to remember that this particular notehead

appeared in one of the percussion options.I should like to know how do i show these different noteheads especially as they use a different clef sign.
