[NTG-context] Variable Caption Locations

I need to have captions ABOVE tables but below all other float types. The default is below, and I know I can do something like { setupcaptions[location=top] \placetable... } for each table. But is there a more elegant way to do it globally? Could ConTeXt have a separate global setup for each type of float caption? Thanks. Tom Browder Niceville, Florida
