Multiple Facebook feeds widget

Hi there

I’m building a site for a non-profit organization with several “chapters”. Each one of these chapters has it’s own page on the site and they would like to have a Facebook widget on the sidebar showing only their own posts.

Been looking around and can’t seem to find the solution for this. It’s either one widget for multiple accounts (all posts together) or for a single Facebook account.

Any ideas to help me please? Thanks
