Any way to get the main Traccar page to open on a predefined report?

Every time anyone logs into my server, they want to see where I've been. So they have to select Report -> Route, then the device, then Today, then Show. They always want to see this first thing, so they have to redo the same report request each time they log back in.

Any way to get that report automatically generated when logging into the main page?

No, there is no way. You would need to modify code for that.

Ok thanks!
