Insert field names in o/p flatfile

Hi Gurus, 

I was wondering if it is possible to insert field names before creating a flat file. I am using 2 excel files as different sources with no field names in it. And I have to modify the file to have different widths between the columns and  have to produce one text file merging two excel files data. Everything seem to work fine until customer asked to insert field names which i know.  But the I am not sure how to insert field names before producing the text file. Is there a way using SSIS without .net or C# code?

Please help me with this.
