Child-parent Facebook pages for donut company

So I am currently doing work for a donut company. They currently have one store in philly and they have a Facebook page for that store.. But now they are gonna be franchising the business and opening up 3 more store locations in the surrounding area within the next few months. So they want to make the current Facebook page a ‘corporate page’ and then make a new Facebook page for the store in the north east and then also make 3 more Facebook pages for the 3 new locations opening. They want the new corporate Facebook page to Parent all the new ‘location’ Facebook pages and they will be the child pages. Does anyone know how to go about doing this ?
