We would like the functionality to calculate UP TO any given calculation. Calculate everything feeding into the calculation specified. Currently you can run an "Individual" calculation by right clicking on any calculation and choosing this from the advanced option. This however only calculates the one calculation. There are times when it is necessary to calculate not only the one calculation, but everything under that calculation as well.
With Tailored Reports going away in the future, This request is a great alternative. The alternative to Tailored Reports (I have heard) is to create a dummy Presenter Report and connect your sources there. That is impractical in most cases if you want to just calculate a piece of your model. Especially if what you are trying to accomplish is ADHOC or one time. That is also not what Presenter Reports are made for so it seems silly that you would use them to replace Tailored Reports.
Please consider creating functionality to calculate up to any given calculation.
