When creating a presentation template you can specify
the location of the presentation template.
Click Select Location to save the
item under a different location than the default location.  Note: - The default location for a new item is based on the current library
and view where you clicked the New button.
 
- This field is no longer displayed once the new item is saved for
the first time. 
 
- Once saved, you need to use the "move" function to change the
location of an item.
