Are you referring to the icon for the Local Data Filter in the toolbar area? Projects have different default toolbars because the window handles multiple document types, but you can configure the icons that appear in this area:

Both inside and outside projects, you can also activate the Local Data Filter from the red-triangle menu for a platform:

Hope that helps,
