Customise chord symbols in Notion on iPad

Dear PreSonus,
I'm writing to you because I'd like to give you a feedback, that I like the
Notion software very much on my IPad. In my opinion more option for
customisation would be really useful in the chord symbol section. Missing
combinations are for example:
C^ (not just C^7)
C+^ (not just C+/^7 in this case the "/" is very aoying, Cmaj7#5)
C•^ or Cdim^
I think that the "^" character is enough, don't need "^7" because the "^" means "maj7".
I write usually jazz, so I can say that this small change would be
great! Could you please renew it in a future update please! :)
All the Best,
Gabor
