How to attach multiple apps... kinds of subapp? I think I saw it in docs, but can't find it

Questions and Help
#1 
app: sanic.Sanic = sanic.Sanic("app")
admin: sanic.Sanic = sanic.Sanic("admin")

app.add_subapp('/admin', admin)

something like this ?

edit: not Blueprints

#2 
app = Sanic("Main")
admin_app = Sanic("Admin")

...

if __name__ == "__main__":
    app.prepare(port=1234)
    admin_app.prepare(port=9876)
    Sanic.serve()

Something like this?
