Feature Request - Notch Filter for Tinnitus Sufferers

[molove]

Would it be possible to add a switchable notch filter to the graphic eq.? I suffer from tinnitus and have discovered tinnitus notch therapy which treats tinnitus by listening to sounds with the tinnitus frequency notched out. In my case 3.1kHz.
It would be great to be able notch out a user defined frequency on top of the Autoeq profiles in Wavelet. It is easy to do on my laptop by adding another Eq after the Autoeq curve. I tend to listen to most of my music via my Android phone and it would be great if I could be able to treat my tinnitus at the same time as listening to Autoeq'd audio.
Thanks

Or alternatively be able to load the graphic eq setting as an Equalizer APO preset
