It is laborious to enter every custom parameter and event through the website. I've entered a bunch of custom events and parameters for our dev environment and am faced with the task of doing the exact same thing for the production environment. Laborious and error-prone. We really need a CSV import/export process. That way I can at least export both environments and compare the two in case I missed something. If anyone is using more than two environments, then lord help them. This is painful. It doesn't have to be.
