CallRail Setting Reset: Add User Phone # to User profile like before LeadCenter launched in 2021

Hello,
I'm preparing for the Lead Center sunset on Jan 26, so I've been reviewing the app before my end users go back.

I remember using the callrail app prior to lead center and back then the user phone # was associated to their user profile at setup. Now instead, we have 2 difficult steps for updates and end user experience:
1) admins have to collect phone #s and manually recall each users' phone # to make schedule updates in workflows. You used to be able to just select the User's name, which contained the phone #, and callrail forwarded the calls to that phone.
2)end users now need to add their phone # when making a call or sending a text. I believe it's just the first attempt, but still, unnecessary if their account contained their phone #.

I'd like to see this be updated before the sunset to help admins and users adapt to the new/old system more easily.
