You can build a customization to circumvent this, but it is actually a security feature. If resource data rolled up, then assigning a resource to a subproject will give them visibility to all parent projects. They would see the entire portfolio and you would not be able to hide projects from resources that have a role in a sister project in the portfolio. Also when logging into Clarizen, they would only see the portfolio projects in their homepage (like a super user) and not the specific projects.
