Hello,
That would require changes from the firmware side of things. Right now you can see script execution event only using logread command. So to answer your question, you cannot add script execution events to system events logs.
But that is valid only if you want to see the log in WebUI. Otherwise, you can simply use the echo command in your script to the system log file and view a new entry if you open the syslog file directly.
Best regards.
