In Add Link dialog box of MyLinks web part, I need to remove few options from "Existing group" and "Show links to" dropdowns. All options which are being displayed for these fields are out of box. I need to display 'Only Me' option for "Show these links to" field. Similarly I need to show only "General" and "Best Bets" options for "Grouping" field. Do you know if there is a way to remove unwanted options from these fields?
Here is the screenshot of the dialog box where these drop down fields displayed.
