Traditionally such chromaticisms may have been notated by simply  
taking 5 enharmonic accidentals to make up a total of 12 pitches (as  
in meantone keyboards). And in the program, they might be reassigned.

But in some cases one may not want to. Take the "Harry Lime Theme"  
from "The Third Man" movie, which starts (written) G G# A G# A. One  
might reason that the first G# is a successor to G, and then it might  
be better changing scale degree, to have it Ab. Then G# and Ab would  
appear close in time: G Ab A G# A.

And in E31 can make glissando-like sequences like G Abb G# Ab G## A.

So in principle, such situations might appear.
