This starts to eliminate each conversation from the trace file as I note it on my spreadsheet. I then go to Statistics > Conversations and check the box for 'Limit to Display Filter.' I now want to filter out each conversation once I note it on my spreadsheet so I go to prepare a filter and chose not selected AB. I do this because I never know when I start my trace files if I'm catching conversations some in the middle so I want to ensure my firewall ACLs are correct so I need the correct conversation flow. I then apply a display filter of (( = 1) & (tcp.seq = 0)) & !( = 1) which (I believe) will only display the initial syn of each conversation.

These display filters are already been shared by clear to send . Wireshark has two filtering languages: One used when capturing packets, and one used when displaying packets.
