For me anyway it's a non issue because I end up always writing in some fucked up scale or regular scale with accidentals etc. If it correctly noted the scale it would also have to let me note the accidentals.
I have similar problems with Push's scales functions. Recently I've been on a sort of mixed scale binge, none of which are available in Push's selections.
The sad part is unlike stringtapper, I'm not that fluent in music theory still, it's like I jumped off into the deep end right away.
An example, not surprisingly called an altered scale:
C, D?, D?, E, F?, A?, B?, C
The thing I find fascinating about this type of scale is that the "correct" spelling very much depends on the context.
e.g. the "normal" use of an altered scale would be to create melodic tension over the dominant 7th chord. So the C altered scale would be used over a C7 chord in the key F - (so the Bb would come from the key signature). In this context the spelling that you gave makes sense as Root, flat 9, sharp 9, 3rd, sharp 11, flat 13 and minor 7th, i.e. the root 3rd and 7th are retained as being the essential notes of the dominant 7th chord, but every other note is Altered and the fifth is omitted all together,
But if you give it the alternative name of Super Locrian and say something like "My piece is in the C Super Locrian mode" then you can treat it like an altered form of C minor and spell it C Db Eb Fb Gb Ab Bb C (with the Bb, Eb and Ab coming from the key signature). i.e. root, minor 2nd, minor 3rd, dim 4th, dim 5th, minor 6th and minor 7th. Then again you could use the same scale name and spelling but treat it as the 7th mode of Db Melodic Minor, with 6 flats and one double flat in the key signature (but only if you are a masochist).
Why did I write all that? mainly because I find it all fascinating and by writing it down helps me to consolidate my limited understanding of these things. And because I've recently spent a lot of time thinking about these things while developing my "fretlearner" web page (see sig) which is currently receiving a major "drains up" overhaul. (Being retired I can afford to spend whole days on hobbies, just can't afford to buy anything)
