To set and determine travel preferences on which locations you're willing to receive assignments, you'll need to use the Location Block List to block locations, rinks, fields, arenas, or schools that you do not wish to travel to.

Not all officiating organizations allow officials to perform this action, though. If your officiating organization allows it, the option will appear on the Administrative Forms page under the Block Systems heading. Contact your officiating organization directly if you're unsure about their policies on specifying location travel preferences via the Location Block System.

You may see this support article for details on using the Block Systems.
