No me es posible enviar autorizar varios registros a la vez con una entidad adicional (Version 1.11.0.2)

[SQL SERVER]

Tengo una entidad adicional que se carga por plantilla y es requerido envíar varios registros a autorizar a la vez, pero solo me permite autorizar de uno en uno. ¿Debo configurar algo en particular?
