How would I get the dataPresenter to paste into the first available (blank) record?  i am currently using:

this.RevPointPresenter.ExecuteCommand(DataPresenterCommands.Paste);

this pastes fine, but I need to have the paste performed at the next empty record, regardless of what active row is clicked before the paste operation.  I also need the paste to still be able to paste over an existing record if that is the selected row though.  is there an easy way to do this?  i was also considering possibly sorting the records afterward, but don't want to go through that every time if possible.
