In the main report insert a subreport. Choose existing report as your detail report.
Make it an on demand report.
Link your main report to your sub report on the project name.
In them main report if you are grouping on the project name place the subreport on the group header or footer.
If no grouping place it on the details.
You cannot have it say the Name of the Project but rename it to say something like "View Project Details" and underline it and make it blue ink. Looks like a hyperlink that way.
