Describe your suggested feature

Can there be a mass migrate button for manga, because when a browser changes names, shuts down ect, having to individually migrate Manga over is time consuming, it's fine if there's only afew Manga per browser, but some have over 800 and it becomes a big task to do them 1 by 1, for example I use mangabuddy now named mangak, and I have 974 different Manga in it that now no longer work so I have to individually migrate them,
