Multiple Score Typesetter font sizes

[Joe and Angela Wilkinson]

    Hi Richard,
    I have a score which needs, say, 3 different Font sizes.
    13 for the Score, to keep pages down,
    18 for most parts
    22 for Guitars which need bigger dots (I'm told).
    It is under development, so needs periodic changes and reprints, and
    it is good when I don't need to remember the size for each Layout.
    You told me how to do this and it works, but is clumsy; for example

• Set overall Score Size as 18
• Go into Score Properties Editor, find (Print) Set overall Score Size and Duplicate it, twice
• 
• This produces a duplicate but without the Execute command button
• Go to first duplicate and, using Advanced change the 18 to 33 in 2 places. Then make it conditional on Layout: Default Score Layout
• Go to second duplicate and, using Advanced change the 18 to 22 in 2 places. Then make it conditional on Layout: Guitar

    Perhaps this just IS Advanced in which case OK, but could it be
    possible to have the Execute Command button as well so that Advanced
    isn't needed? 
    Best wishes
    Joe
