T-Mobile Multi Line settings with Verizon ROM

[barnesk9]

Hi guys, I'm hoping that someone can help me out with something. I have a Verizon phone and a T-mobile phone with Digits. I want to use the S8 to have calls from both phones work. I know that if I use the T-mobile app I could use the multiline settings and add a digits number but I was wondering if it's possible to access them in the Verizon ROM at all?
