Custom error messages in dataloader error file

Can we write custom error messages in data loader error file by apex?? I mean when we upload a file by data loader if it fails it shows predefined messages given by salesforce in the error column. I need to change that error message by my own custom message.. 
Any idea on this??

Hi Anujit,

I cannot understand why you want to show custom error messages in Dataloader. As dataloader bascially throws error if it is able to insert/update data which happens because of required field missing, validation rules or any other customization.

What exactly you want to do.

Thanks,
