Where is the dual sim menu for ringing on D6633 in Android MM ?

Hi guys, I just made the upgrade to MM. I realize that the double adjustment menu sim D6633 can no longer choose two different tones for two SIM cards. Is there a mod for this? 5.1.1 it was possible... :crying:

I've researched the forum but I have not got my answer.

In advance thank you very much to the community.

Increasing volume steps for lower notification & ringing volumes.

As the title says, does anyone know of a way to add volume steps to the OP3? I am using OOS and have added 35 steps to the media volume using GravityBox but I can't find any Xposed modules or zips that increase the steps for notifications & call volume, I find both to be really loud and I don't want to use the slider to keep the phone on permanent silence.
