Hi Mark,
One of the benefits of the Foundation Template is that it is easy to add additional templates to your core Foundation template. You can use the Tiller Labs add-on to access and try out new compatible solutions. As updates are made to these various solutions, you can manually refresh your template to make sure your spreadsheet has the latest functionality. Likewise, as you experiment in your template and make changes, you can always restore your template to the default settings.
