Edit the result shown in ​a list for a standard BO

Hi,

Anyone know if it's possible to edit the result shown in a list for a standard BO that is read-only using PDI?

In the example below i want to filter out which activities should be visible based on the user recording their time. As of now it shows all activities. So basically, what i want to do is to create something with PDI that works the same way the advanced filter does in the GUI.

Regards,

Pierre
