To better track cost of a project, it would be nice to have a Project ID field in the PO request. This would need to be a data point that could be reported on so that you could run a purchase report on all purchases with Project ID XYZ.
Work Log Summaries. Currently you can associate a Change, and a Service Request to a project however if there are work logs created in any of these, they don't carry over to the timesheet in the project. It would be nice that once these are linked the timesheet would reflect these work logs.
