Kobo Glo Shelves / Folders

I have a list of of some 200 authors that I want to create shelves for then insert approx. 1000 associated titles into them. I want an easy way to do it.

This must be a common requirement and I thought I might find a useful utility to help me through it.

I thought that perhaps it could be done using Calibre but have not been able to discover such an option. Can anyone please help here?
