Impress editing links

I have Impress presentations with link to video files. The videos work fine. However, when I want to change the link or change the path to the linked file, the only way that works for me is to delete the video and then add it back. Once the video is linked, I cannot see anyway to determine what the link was and edit it. There is an Edit Menu item labeled “Links to External Files” but it is always grayed out. Is there a way to activate this menu selection or another way to see what is linked and the path to the file?

Editing Hyperlinks

Hyperlink dialog box

The outline of the linked video is visible on the slide. However, there is nothing available on the main menu or on a right click menu, that allows the link to be visible or edited.
