I think it would be super helpful if there was an option to name or label a phone number with the person's name, especially in situations where I'm working a deal that involves multiple people who aren't necessarily co-signers.
Right now, the only options are “Home,” “Work,” or “Cell,” but that doesn’t always give enough context. For example, I might be speaking with a customer, their spouse, a parent, or even a third-party like an insurance agent — all connected to the same deal. Being able to custom name a number like “Sarah – Mom” or “John – Insurance Agent” would make it much easier to keep track of who I’m talking to and avoid confusion.
Even in cases with co-signers, being able to label whose number is whose would be very useful.
