When you create a View formatting in Manage views of PWA Server settings. There is no out of box option to show a specifc task (collapse every tasks except one ) but on another note if you have the specific task is standard on each project & lets say
on Outline level 2. You may setup the view to show the Outline level 2 in view formatting.
You may create a custom PDP page with JSgrid or standard grids which can show the data as desired.
