A workaround:

If, for example, you need a CdimMaj7, spelled in closed form from bottom to top, C,Eb,Gb,B:


Try a B/C, which spelled the same way would invoke at least C,B,Eb,Gb (with the flats being enharmonics actually but sound is the same).

If you really want a CdimMaj7 with the Cdim "all the way" you would need to add an A in there.

Try B7/C

As always with a chord workaround of this nature and the BB styles engine, you may find that some styles pick better inversions for the intended purpose than others. Open chorded styles will likely be the "easier" ones to please in this regard.


HTH,
