Contact With Multiple Phone Numbers Indistinguishable In Messages On IPhone

I have a contact with two phones - for instance, John and Jane Doe. I want to text them each separately, and easily see who I'm texting. But in the Messages history, it displays "John and Jane Doe". And it's a hassle to click on the message, then "Contact", then "i" to see which is colored blue.Â

I've even added custom identifiers to each phone number in gmail contacts. Instead of "Mobile" or "Work" I used their names, "John" and "Jane". I'd like to see those custom identifiers in the Messages app.
