I don’t see a “customize” command, so I’m guessing the answer is “no”. You might be able to do it through registry hacks…but not through the GUI directly. Not surprising as INGR has always been concerned with providing too much functionality in the product and thus potentially cutting off GM or GM Pro sales.

I’ve done it in the past. But I don’t have it setup yet. I’m also looking at using FME and/or Schema Remodeler to do this as opposed to materialized views. If you’re looking for more information on the subject, I’d highly recommend reading Simon Greener’s blog “SpatialDB Advisor” – http://www.spatialdbadvisor.com/. He has a section on Oracle Spatial – http://www.spatialdbadvisor.com/oracle_spatial_tips_tricks. Just do a text search for “Materialized” and you should see quote a few links. Simon writes a TON. All very valuable.
