The ability to select module measurements in Formula scope

Please, add the ability to select module measurements in Formula scope. With this feature you can use both manual input and formula in one LI, not only using the built-in versions, but also the lists and subsets. Advantages:
1. Reducing the number of Line Items. No need to duplicate LI for fact and forecast input.
2. Simplify the dashboards. Reducing the number of LIs allow to focus on what's important.
