a very important information goes missing when we convert a project into a custom item.
A normal project has the attribute "Time Spent" that aggegrate all time entries from tasks and subtasks. When we change the item type then this attribute is gone. So we don't have the opportunity to check how much effort has already been invested in this project.
1. Time Spent is available in a normal project
2.Item Type is changed
3. Time Spent is not visible
