Using Components in Defaults

I have a mapChunk blueprint that contains ExitPoint SceneComponents so that I can place these chunks next to each other to form a contiguous map. To generate this map I wanted to have a list of these ExitPoints in the blueprint of each map chunk as an Array of SceneComponents that you manually set in the Defaults page. However the components of a blueprint do not appear to turn up when you try and add them to the Array. Is it possible to access the components in the Defaults section? Or should I just create a function that returns these?
