Documentation framework - "view source on GitHub" link for multiple components on single example page

With multiple components on a single examples page, should we have multiple "view source on GitHub" links? Are those links useful? Currently they link to the actual page the link displays on - which is the example MD file. IMO the link may also be more useful if it linked to the component root dir on GH (eg, gh.com/patternfly/patternfly/src/components/Alert).
