Non-Depreciable/CIP Assets

For large company projects we would like to set up CIP assets as non-depreciable assets and then begin depreciating them at the completion of the project.  How do you recommend doing this for assets that come through the AP interface (we are very rarely setting these up in Basic Add)?  Should we set up a non-depreciable asset profile or category and then later recategorize them to a depreciable profile or category? Or should we run them through the interface and create the assets and then change them to non-depreciable in the Define Tax/Depr Criteria panel?
