You can color code your vehicles. The checkbox next to each vehicle of that type in the mission dispatch list will appear in a specific selected color.

To set this up, select any vehicle of the type you want to color-code.

Click on the vehicle type.

 In the details section, click on the empty color field to choose a color, or enter a hex code manually.

Once saved, the checkbox next to all vehicles of that type will appear in the selected color, making them easier to identify during dispatch.
