Graph defaults are set to "daily" so whenever I want to add a trendline it tells me I can't do so without changing the graph type to "session data" and it's just a really annoying extra step to have to go back out to the graph, change from "daily" to "session" just to go back and add the trend line.

Could it someone be that when we add the trend line it automatically changes the graph type from "daily" to "session" so that we don't have to manually do it?
