Create Fuel X-ref for a single facility at a time

The create Fuel X-ref has to be ran for all facilities or it ruins the Fuel X-ref for any facility you didn’t run it for. This can cause major issues for companies that have multiple facilities. Every time they add new vehicles, they are supposed to run that to update it. They would have to get every one out every single time. Either add the ability to run it for one facility at a time or a way to run it when people are in the system.
