Any way to copy chat only specific date?

Hi every one
Sorry if this topic is already posted, I try to search it but can't find it.

I have a problem with copy chat from bbm that every time I copy chat from a friend 's message, it always copy chat the whole conversation from the beginning of the chat. Even if I end chat (o turn on save chat history) .

Is there any way to only copy specific date of my chat? So I don't need to delete part of my conversation. Many times I only need a part of my conversation, or only one day 's conversation. But every time I copy chat, I have to delete the rest. In os7 we have chat history based on dates.

Anyone can help? Thanks
Selwyn.
