When I was in school, I didn't see any established explanation of
diminished chord functions that made sense to me, but anyway, what you
described is known (to me :-) as Schoenberg's harmony analysis and,
while it partially make sense, I don't entirely agree.  In jazz,
diminished chord has 7th, which creates two set of tritones, that
produces 4 directions if you want to make a traditional resolution.

Then if you look at them, diminished chords' tritone aren't really
moving as expected, i.e., I dim7 and V dim7 are followed by same root in
the tonal context.  There are many reasons we can't call them
theoretical 'resolution'.  They are just psychological gravity, so, no
arrows, at least to me.

Thanks for the suggestion of using Text Exp.  That was how I used to do
but I switched to DTP application our of frustration, but that was when
Finale still didn't have auto-placement.  I shall try it again.

Regarding the standard, I wish if I were world famous to tell everyone
what I say becomes the standard!
