Reports - activity due date "smoothing"


 I have multiple projects with multiple activities within each project (activities are identical but have different start dates). Example below. So if I have 100 projects and Stephan Voges is responsible for GL quotation, apply corrections etc. (as below) for each of the projects I would like to draw a report for him so he can look at all his activities across all projects assigned to him and stagger the dates so he can cope with the workload. Can anyone show me how to do this, please?
