Heroes from campaigns in the editor. Auto-translated

I remember that in Heroes of Might and Magic V, the Heroes of the North (Editor) had heroes like Lorenzo, Orlando, and Andreas available, but I didn't see them in Tribes of the East (Editor). Is it possible to bring them back somehow with a mod, or is there something I can click in the editor itself?

Place any hero, select him in the left panel, find the "Shared" line, click on the "..." to the right of it, and find the desired hero in the list.
