Secret note section in a login/password item

I store my backup 2FA codes in a my Login items under Notes.

With possible bad actors being more and more able to read screen contents through OCR, I would like to request that besides the open 'Notes' section in Login/Password items, we also get the possibility to add a Secret Notes field.

Be aware: This is not the same as a password field because this secret note field should be able to contain multiple backup codes. And I don't want to create e.g. 8 password fields for each code. When I put these in a regular password field, they wrap as one line. I need to be able to store each item on a different line.

Thanks for considering.
