Examples:
Week 1 to 4 belongs to Month 1, which belongs to Year 1. Need a line item with contribution function where if you select year level, shows Week 1 as a contribution of Year 1, or Month 1 as a contribution of Year 1, depending on what time level you are looking at.

Need a line item with contribution function where if you select Company level, it shows Subclass 1 as a contribution of Company, or Class 1 as a contribution of Company, depending on what product level you are looking at.
