I have never tried this, but assume that you can define your own header class programmatically, adding new property 'ID' into definition. Then, in run-time, you should remove standard header (RemoveObject) from grid.column, and add (AddObject) new header from new class.
Unfortunately, you cannot add any additional objects to a header, because this is not container.
