Adding delete button into a Portal screen ( probably setting in the WAD)

Hello,

When you execute in the portal a query you get some results. You have the opportunity to Save this repport. You'll get 3 tabs, Favorites; Bex Portfolio; My Portfolio.

When I want to delete some favourites is this impossible, I want to have an delete button in this screen. Is this possible? Probable you have to open the Web application Designer to solve this.

Need some help to fix this

Kind regard
