I am using SP2013. I'm looking to create a page template which will be used on all project pages within a site. I have Department pages using the Team Site template. Within each Department, we have a Projects list. This list gives a high level summary of what's going on in each project. The list item has a link to the a detailed project page. Each project gets its own project page. I have created a 'template' page which I'm using as the starting point for each new project page that gets created.
The problem I'm having right now is that every time I make an update to a project page, I have to go and update 30 other project pages. Is there a way to create a project page template for these pages so if I make a change to the template, it will push through to the rest of the pages using this template.
Also, please excuse any mistaken terminology. I am new to SharePoint.
