Default Group for Time Entries per Project
You can now define a default group for time entries on a per-project basis. This setting is configured by the project manager and applies to all project members. As a result, all newly created time entries in the project are automatically assigned to the defined group.
This feature originates from real-world use cases in consulting environments, where it is important to ensure that all time entries are consistently recorded in the correct group for billing purposes.
