Thank you for the question. If you switch to the HTML editor while editing the configurators description then the 2000 character limit is not imposed on the code itself. Therefore, you can just paste the HTML code into the HTML editor and you will be able to list using the HTML template.
Hope this helps.

I have realised that the maximum number of characters is only 2000 for listing via LW. If we implement a HTML template to be listed, how can this be overridden to allow more than 2000 to include the item descriptions and also for HTML template?
