Pacallama

I've just migrated to Alfred from Quicksilver. Really enjoying it, however I would like to be able to set something as the default first result for a certain letter. For example, if I have multiple folders with similar names such as Folder_1 Folder_2 Folder_3 Folder_4 When I open Alfred and type "Fo" I want to be able to set the default first result to Folder 2. It seems like if I navigate to it it starts to do this automatically over time, but is there a way to set this manually?
