In the settings, you can specify that “employees can mark working time as a 'customer change. '”

You would expect that with this setting, similar to “Record travel time”, a check mark appears on the AZ booking that can be set. But that is not the case.

Only after booking the AZ does an additional check mark appear in the list of time bookings. The different display and process of marking is not entirely conclusive.

Suggestion: In both cases, such as for the travel time, the AZ bookings should be marked with a checkmark when booking time.

In the list of hours, the checkmarks should be described in text for better readability, as if requested by the customer.
