Saving a design iteration in Windchill

Is there a functionality in Windchill 11.0 where you can save a snapshot or iteration of your assembly where all the associated parts and drawings can be saved at the same iteration.

For example, if I had an assembly with parts and drawings where I want to save that design as-is so that it can be restored or retrieved in the future.  This would be in the case that the design continues on a new course, that ends up not working out.  I would like to go back and retrieve the design iteration that I saved previously.

Thanks
