Different summary calculation for a specific summary column in a Custom Summary Row

I have a custom summary implemention. Let''s assume that I have three cols (C1, C2, C3). I would like to the last column (C3) to have a different summary calculation than that used for the other columns (C1 and C2) in the summary row.

Is this possible? I would think it is possible is I could dynamically get the name to column from the ''SummaryColumns'' collection.
How would I specify this different custom calculation from the default calculation in my custom summary class?

thx.

I think that i found a way...

public static ISummary CreateSummaryMethod(SummaryDescriptor sd, Record record)

if (sd.FieldDescriptor.GetName() == "MyCol")
{
///my column based logic
return new Summary(...);
}

Ok, another question...

Can I do the same for the built in Summary columns, i.e, for specific columns, plug in my own calculation or display a custom text without resorting to creating a custom summary
