There are situations where quick jotting down of music is needed. If the chord style has more information, it can be effectively converted to a full-fledged notation latter on. Thus the Roman style notation which has the advantage of applying to any scale without the need for a transpose could be one of the quick tools. I consider that if the Roman style chord has yet more information contained in it, it could be a more useful and effective tool.
For example, let me consider a bar of music with three notes viz. E (a crotchet value), D (a Crotchet) and C (a Minim). This bar could accommodate four chords say I, V, VIm and IV in C Major. When I provide just the above information, someone may play it as: I (1513), V(5572), VIm(6361) and IV(4461) where I intend it to be played as I(1153), V(5752), Vim(6131) and IV(4641). The numbers indicate the degrees of a scale. Thus providing the musician more information about the chord/s would help.
This is handy in many situations where quick jotting down is needed. I could jot down quickly the music as I record on the spot, for example, so that I could use the information for further working on the piece. Thus, if Finale provides a new style say Roman B, where it allows descriptive information of the scale degrees in a Roman Chord, it would help.
