Keep users on measure page when drilling down a portfolio project

When on the measure page of a portfolio the system displays the list of projects from this portfolio.

When clicking on a specific project, the system currently sends the user to the overview page of this same project (see attached measure_portfolio.gif). This is not the pattern expected on the measure page. Users come here to be able to drill down through the project folders.

Also, we already provide a way to the user to jump directly to the overview of a specific project with the link icon.

What should we do?

Allow the user to drill down through the project folders.
