Right.  There should be an "easy mode" for adding custom fields which 
puts them into some area of the bug form along with a "manual mode" or 
the like the administrator can use when she wants to add them to the 
"edit bug" template by hand for control over their placement in the UI.  
This should be selectable on a per-field basis.
