Feature request: Private and business trips

[lukasha1]

Is your feature request related to a problem? Please describe.
More and more companies require that private and business trips be distinguished. Unfortunately there is no easy way in traccar to do this.

Describe the solution you'd like
Private/business selection can be made in two ways:

• calendar (set working hours), after these hours - private travel
• Reported by devices (more and more devices have a physical button, others can use DIN and calculated attributes).

The trip report should include a selection list: private, business, all. And an additional column that will display: private, business, private/business (if during the trip there is a change in status from business to private or vice versa). The same column should be in the Excel report. It would also be useful to have an event - change to private/change to business.

Describe alternatives you've considered
I considered using the Driver attribute, DIN and calculated attributes, but then it is not possible to display only private or only business trips. This solution does not allow you to use the calendar.

Additional context
I think this feature would make many Traccar users happy
