ColumnMapping and Typed DataSet

I have a typed dataset, and I want to set the ColumnMapping on some of my columns (ones whose Expression property is set - they're not actually holding any data) to MappingType.Hidden, so they're not saved in the XML file.

Currently I'm setting the ColumnMapping property on each of the columns in the code thatuses the DataSet, rather than in the DataSet itself. This seems less than optimal.

Ideally I'd like to be able to set the MappingType from the Properties window in the DataSet designer, but since I can't do that: Where's the best place to set this property? Is there some method I can override in the .cs file for my DataSet?

Cheers,
Matt
