You could use a boolean db field 'ShowLinkOnPage' on your Page class, then create a CMS CheckboxField for it, and finaly create a function like this on your Page_Controller:

public function LinkOnPageChildren() {
    return $this->Children()->filter(array('ShowLinkOnPage' => true));
}

and use <% loop $LinkOnPageChildren %> in your template.

Or just use <% loop $Children %><% if ShowLinkOnPage %>... (Whichever you feel best)
