Decision Tree English Rules and Dependency Network in MS SSAS


I created a Decision Tree model in Microsoft Analysis Services (SSAS, Visual Studio 2010). There are two tabs in the Mining Model Viewer tab: (1) Decision Tree that shows a tree itself, and (2) Dependency Network that shows the chart of most important variables.


enter image description here


On the Decision Tree tab I can click on each individual leaf and see the English Rule for that leaf. Is there a way to get ALL the rules at once as a list with the case numbers?


The Dependency Network tab has a slider that you can move to see which variables influence the decision tree most. Is it possible to get ALL important variables as a list with their "importance" number?
