Creating Content Templates

I am looking for a plugin or feature for
creating content templates, which you can use as the basis for a new
page and then modify as required. I am using a data feed on my website and manually add products myself, I would like the data feed to be able to automatically pick up the feed from the title on the page. On an old site that I used to own, which was not in WordPress, but was custom made, when I added a new product the data feed would automatically find the relevant products that matched the title. The feeds could also be edited if a product was not needed. Here is an example page, you can see the product feed towards the foot of the page.

Any help is appreciated, thanking you.
