How to force kirby to load a static html page using the custom response type in the router?

Something like this seems to have worked in kirby2.

Display content from HTML file on a page?

I am at the stage of adding content to a site. The content, which was created in another program, consists of an HTML file and a folder of images. Is it possible to add these as files to a page then have kirby use the content of the HTML file on the page? Thanks
