Difficult chord progession

[Nextom]

I'm trying to put in a rather unusual chord-progression. (It's from this piece https://www.youtube.com/watch?v=dQEmaj9C6ko, and the progression has been analyzed not by me, but by someone with a Ph.d. in Music, so it should be correct). This guy wrote up the progression (in G minor) as Am7/G - Cm7 - Cm7/G - Am7/G. In the piano roll, it looks like this:

Now, my problem comes, when I try to put that into Rapid Composer. When I put in the chords via their chord names, they come out differently from the original. When I put them in via keyboard RC gives them rather funny names: . RC also doesn't seem to find a rule, under which they all fit in.

My question is now, how to deal with that. Have I just picked that one "impossible" progression, that's just too much to handle for RC? Should I give up and forget about it or is there another way?

The first, third, and fourth chords of that chord progression look valid. However, that second chord as it appears in the piano roll (Bb-C-D-G) might actually be one of the following:

* A#6/9
* C9sus2/A#
* D11#5sus4/A#
* Gm/A# add(4)

The second chord on the piano roll is a Gmadd4 (which is just one name for these notes).
See the differences between that chord and the inverted Cm7:



BTW I love that BoC song...

i love BoC unusual progressions too. maybe somebody could work up a small library of them for RC?
