Lets say I've got an object model, where I have many collections of the same type.

For example something like

class StockMarketData {
  List<SummaryData> WeeklySummary;
  List<SummaryData> MonthlySummary;
}

class SummaryData {
  DateTime DateTime {get; set;}
  double Value {get; set;}
}

Those lists will map onto database tables.

If you actually use L2S to generate a model from the database you will get something like:

class StockMarketData {
      List<WeeklySummaryData> WeeklySummary;
      List<MonthlySummaryData> MonthlySummary;
    }

Even though WeeklySummaryData and MonthlySummaryData have the same shape.

Is it possible for Linq to SQL to create tables from a database of summary data, but get each table to contain the same type (such as shown in the top example).
