Multiple notehead parentheses and slurs?

Hi everyone,
I’m having a hard time trying to achieve this result.

As you can see, I need to put a set of notes between parentheses. Also, I’ll need to do the same thing only with the slurs. Is it possible?

I just attach them as staff text to the first and last chords, turn off collision avoidance, and position them manually.


Thank you!
