Driving Logbook App customize questions

We would like to make some changes to the driving logbook app.
Is it possible to send me the print.php file which is used to print the excel document?

Another question:
We have a device with some trips between 3-may-2017 and 5-may-2017 (id: 14699508 if that's of any use)
Which have a private status using a custom sensor.
How can we use this data in the report? I can see the events.sensors is always empty when I print this...
