Warning for medication x1 order given in ED

For ED transfer patients given a x1 dose in ED and there is a new order for the same medication. We would like a warning that a dose was given and the new order needs to be retimed. For example, Rocephin was given as x1 in ED and the admitting provider orders Rocephin Q12. If the new order hasn't been retimed by the provider, it shows due. Is there a way to add a warning that it has already been given?
