Currently if you want to create a reoccurring item, this has to occur at the top level of a project. It would be helpful to be able to create reoccurring tasks at any level of a project.
Setting them up at the top level means you end up with reoccurring tasks sitting outside of their activity area.
For example, my typical approach is to have a task called Project Management and then setup any Project Manager tasks in this area. One of these is producing regular status reports. These may be required weekly, fortnightly or monthly depending on the size and complexity of the project.
