Is there a way to view the preamble pattern in XCTU?

I’m using XBee Pro S3B 900 MHz modules. I’m doing a bit of a reverse engineering project that needs the preamble structure. Right now my preamble ID is set to 0. Is there a way to capture the preamble bits using XCTU? The user manual states that a preamble pattern is used but no other information is given. Perhaps there’s a way to write a Python script that captures this information?
