how to post already published hundreds of (old) k2 items

hello,
how to post already published (old) k2 items to social media?? any shortcut on "social backlinks" component for that??
because we have thousands of k2 items already published (old) on our web site so you need to put a shortcut or setting on "social backlinks" component. it is not okay to go to every k2 item on our web site and save/update it. and when will you release it?
without that option, it is not useful to buy your component at the moment
