How to print multiple email conversations

Hello I am hoping that some clever wizz can help me:
I am using em client with my gmail
I need to print thousands of emails to a PDF  for court but I only want one email per thread. Because each email contains all the email history, I am getting multiple copies of the earlier emails. Does this make sense?
I guess what I’m asking for is to able to print the last email for each conversation and that includes all the history for that conversation.
As I have so many I need some sort of automated process to do it
Can any of you help?

Hi Daniel,
unfortunately there is no automated process in eM Client that I could think of that would solve your issue.
