Customize the AEM console

Hi ,

 I need one help we need to customize the livecopies location to site level . 

Means , /libs/wcm/core/content/sites/jcr:content/actions/selection we have drop down so here we need to add one more section as livecopies which is located in /apps/wcm/core/content/editor/jcr:content/content/items/content/header/items/headerbar/items/pageinfopopover/items/list/items/livecopies 

Any idea how to proceed with this customization in console drop down ?
