Help Touchwiz - Text message ID

[HepC]

Hi.
If I have a contact with two mobile phone numbers is there a way to determine which number I am sending a text message to? I know that if you compose a new message I can select the correct number but if you already have a thread going, which I sure most people just jump into to send a quick text, you have no idea which number it is.
I will probably just seperate the contact into two, but just checking if I am missing something in the touchwiz setup.

thanks.

Not on stock but go SMS has this feature.
