The Time Entries report now understands project roles. You can answer questions like "how much time did our implementation consultants spend on this account?" without exporting anything.
See the breakdown
Go to Resources → Time Entries.
The summary cards above the table split time tracked and, if you track billable time, billable cost by role.
Each row shows a role pill next to the team member's name.
Filter by role
Click a role in the summary card to filter the table down to that role.
Or use Filter → Project Role to pick one or more roles. Choose No role to find time from people who are no longer on the project, or entries with no project.
The summary cards follow your other filters too, such as project and date range.
