Displayed number customize on each device Merged

As an assistant I have several numbers that are routed to me. I have the physical phone set up so that I can see the number they're calling, but only during the call. I would like to be able to see on the app what number the caller is dialing, so I can represent an office in Gilbert or Las Vegas the same without asking them. I would also like each user to be able to easily call from any of our numbers and that be the displayed caller ID. I can select it on the app but not anywhere else and the other users are not able to.

I would also like to click my call history list and know which number they called from. Not just during the active call. I would also like each of my colleagues to be able to do this. Going to the report to look at this while on an active call is a bit much.
