Right now each transaction has a "Summarize" button that excludes it from being used to calculate the satisfaction score. It would helpful if there were a way to exclude a transaction from the "all requests" monitor. This way for particular transactions you can set a higher threshold than all the others.
An example use case would be if you have an application which uses an external API that is slow. You can seperate the transactions that use this external API from the rest, that way you can still identify performance issues in your code or infrastructure.
