Need help : setting correlation id and dynamic configuration at message mapping in PI 7.4 Single Stack

Hi Experts ,

I  am looking to correlate file name  to send the request and response using Sync Async Bridge in PI 7.4 Single stack .

As we can set the correlation ID as message ID to send Sync Async request response . in the same manner can we set the correlation ID based on  FileName

Please let me know if yes then how can i achieve this . Do i need UDF ?
