Chord Sequencer & using "alt" chord types?

[brunorc]

alt1 & alt2 have fixed Chord Types as follows:
    alt1: I=triad, II=7th, III=triad, IV=triad, V=7th, VI=7th, and VII=6th
    alt1: I=7th, II=7th, III=triad, IV=7th, V=7th, VI=6th, and VII=7th

I landed here, looking for "alt" chords in Chord sequencer and got puzzled a bit, then checked the manual. Both options are written as "alt1:", and while the typo is obvious, maybe is worth fixing. However, I can also hear that "alt" shapes have extra notes (actually, would love to have 7sus4 as one of the alts for V) so it would make perfect sense to have those available in Chord Sequence (if firmware could allow that).
