the company i work for recently requires all employee to use company iPhone for purely company use and now we have 2 phones to carry, one work one personal.
in the past my CT was linked with my work phone, but now that i added in my personal, i noticed that it doesn't auto select. Or is there a way to set it up so i don't have to manually go in to link it?

 

I have 4 paired phones on my CT, it selects whichever phone is, effectively, closest to the car.
