So every now and again I'll be in a conversation with someone in particular, and they may text me from another phone that I have for them in their contact card. If I understand correctly, iMessage will simply show "iMessage with <number>" when it changes the reply to go to the other number. However, every now and again I'll find this bugged out and it'll randomly switch numbers. I'd personally rather keep 2 separate conversations going if it's two separate numbers. Is there any way to force this, other than creating a separate contact? This only happens with my iMessage app on my Macbook Pro. iMessage on my iPhone keeps the contact separate like I'd prefer.
