I have one generic page (cookie cutter) in Prismic that I want to use for serving multiple URLs. Within this Prismic page I want to have some way to have placehoders that can be replaced beforing serving the final content. For example I would like to change the content heading (Rich Text Field) to make it specific to URL being requested. That way although its a generic page I still can make it bit unque for each URL.
What would be the approaches to achieve this requirement?
