Yes, loading the Industry Packs specially created for Daylite, will not affect what you already have in place, it will however enhance it, by providing Industry specific details such as Categories, Keywords, Pipelines and more at no extra cost. Once the Pack has been added to your database, there is no way to isolate and extract that information should you choose not to use it.
Important: You cannot remove the industry pack settings once added. If you want to trial the industry pack create a free Daylite Cloud account and review the new settings before committing.
