The cover letter is not retained; it is throw away information. Each patch should have a coherent changelog that explain why the patch was done and explain non trivial things in the implementation. Simply copy/pasting the same story in multiple patches is not right either, for the simple fact that the patches were not the same. You did a different thing, so you need a different story.
