Can you seperate TCP_FLAGS to CLIENT_TCP_FLAGS & SERVER_TCP_FLAGS when ntopng dump flows via syslog?

Separating TCP_FLAGS into CLIENT_TCP_FLAGS & SERVER_TCP_FLAGS in ntopng Syslog Exports

When nProbe exports flows, TCP flags are separately reported as CLIENT_TCP_FLAGS and SERVER_TCP_FLAGS. However, it seems that ntopng merges these two fields into a single TCP_FLAGS field when exporting flows via syslog.

Is there a specific reason for merging them into one field?
If not, would it be possible to separate TCP_FLAGS into CLIENT_TCP_FLAGS and SERVER_TCP_FLAGS in ntopng’s syslog flow exports?
