Scent Trunk 2.0 - Custom fragrances, using data to make better scent products

Tried the scent test kit and absolutely loved the experience! It was a ton of fun experimenting with all the different scents and figuring out what I liked best. If I want to change my fragrance down the line, can I choose to be sent another scent test kit? And will the scents in the test kit vary as you continue to iterate?
