Is there a way to create bookmarks like with pdftk?

From How to Export and Import PDF Bookmarks:

Export PDF bookmarks, metadata, etc. to a file:

pdftk C:\Users\Sid\Desktop\doc.pdf dump_data output C:\Users\Sid\Desktop\doc_data.txt

Edit bookmarks accordingly:

BookmarkBegin
BookmarkTitle: PDF Reference (Version 1.5)
BookmarkLevel: 1
BookmarkPageNumber: 1
BookmarkBegin
BookmarkTitle: Contents
BookmarkLevel: 2
BookmarkPageNumber: 3

Import PDF bookmarks from a edited file:

pdftk C:\Users\Sid\Desktop\doc.pdf update_info C:\Users\Sid\Desktop\doc_data.txt output C:\Users\Sid\Desktop\updated.pdf
