On my iPhone I have a well-curated Contacts list of all of my friends and family.
I also often want to name the phone numbers of more temporary "contacts": one-time business deals, recruiters, friends-of-friends for a single weekend, etc.
I don't really want to add these people to my Contacts forever, but I do want to read their name on Caller ID when/if they call.
Does iOS have any concept of "second-tier" contacts that are saved but not listed as "Contacts" in my address book?
How can I save and name phone numbers but keep them separate from my true Contacts?
