We have found that when ideas get posted through out control portal, they may result in multiple features.
There is currently no mechanism to take 1 idea and either promote it into multiple features (not sure what that would look like), but at least allow it to be linked to multiple features.
Since this idea was last updated, we have added many more options for promoting an idea. Now you can promote an idea to an epic, initiative, or release and then break it down into features for delivery.
I will learn how to type next.
