Give users the option to modify the guidelines by which Performance Advisor provides its suggestion. A way for customers to input context so that Performance Advisor can give better suggestions

Customers have been commenting that Performance Advisor suggestions are too aggressive at times for things such as creating/dropping indexes. They note that the frequency that they query something Performance Advisor suggests creating doesn't warrant the memory usage it would take to create that index. On the other hand, they may not use an index frequently, so Performance Advisor suggests dropping the index, but that item is critical to their application performance.
