How to limit wp_get_archives by author?

I’m actually wondering how to get both wp_list_cats and wp_get_archives to list URLs that will limit any results by author.

Right now one of the links that wp_list_cats lists is:
/index.php?category_name=poetry

I’d prefer:
/index.php?author_name=Nabha&category_name=poetry

Any thoughts? I haven’t been able to find any plugins by searching — but it seems like something that ought to be really simple (for me or someone else) to do.
