I am sure if you block someone you could go back and unblock them also at a later date. This should bring your chat history. I have not tried this but am assuming this is how it would work. Not delete the chat history. You could find the list of block numbers on your profile then settings click on privacy and the blocked list should be the last item.

I had the same issue in the past. Now I am using Notes and copy the information I want. I also found out I could copy the photo also. If you find info on web site and want to keep the details it also helps to keep the photo.
