Does Custom Sidebars Pro work with UpFront/Spirit?

I am looking for a way to streamline my workflow until UpFront puts in place the page cloning, template editing, etc. that is badly needed. Build each page individually? Are you kidding me? These elementary, but glaring, weakness are rapidly outweighing what could be a fantastic system.

Simple question:

In Spirit, on the Appearance Menu, there is no Widget section as there is on other normal WP sites.

Will Custom Sidebars Pro work on Spirit?
