This project is available as a plug-in to the dispatch module.
This plug-in adds the ability to manage a set of seals that are applied to trailers and other containers.
There are two (2) types of seals in the system: yard and customs.
Customs seals must be tracked.
This plug-in presents a list for both types of seals and allows for assignment to people and usage on a container.
As usual all changes are timestamped.
