Edit/hide Epi default help text

In the Page information area in Epi UI/EditorGUI (in the grey area at the top of any page template), you find information about the current page, including help text for the attributes. The helptext for 'Display in navigation' says, e.g.: 'Select this check box if you want to display the page in site navigation. If not selected, the page will only be displayed in listings.' The last sentence is not applicable for our implementation, as our listings are based on tagging, not page type, so it will not display in listings - regardless of if the checkbox is selected or not. So our request is to be able to edit or hide this Epi default help text.
