1- C7 augmented or C5+7 or C7 aug ????

Tried several coding without success.

2- I noticed sometimes IrealB displays the chord with an inversion not convenient.
Would it be possible as an addon to code the inversion we want to play on the piano.

Even if I code my chord with the bass : Cm7/Bb for instance, the chord is not displayed the way I have to play it.

Having a code for the correct inversion would be great.....
