Quickly find a component in DxDesigner

Is there a way to find and obtain a reference to a component without iterating through all the components? For example, if I want to find the component with reference designator 'J1', I currently do (in Python):


dxdApp = com.GetActiveObject('ViewDraw.Application')
schName = dxdApp.GetProjectData().GetiCDBDesignRootBlock(dxdApp.GetActiveDesign())

for comp in dxdApp.DesignComponents("", schName, -1, "STD", True):
   if comp.Refdes == "J1":
       # Do stuff with comp
       print "Found my comp!"


Obviously, this O(N) operation is not ideal for large designs.  I can (and currently do) create a dictionary cache (e.g. { "J1": comp, "J2": comp, ... }), but initializing that still takes 20s+ on some designs. Plus, if the design changes while my automation is open, the changes will not be reflected until I recreate/modify the cache.


If the API does not have a O(1) search solution, can we get one? Thanks.
