When gathering via routes
 

Excuse me if this is stated elsewhere. It doesn't seem like I am able to select multiple gather types IE small thorium/iron ore as a preset to routing. I can select 1 type, or all types, but nothing in between. I would like to be able to select specific types and calculate a route for doing so. Is this possible and if so how is it done? Thanks for your time.

Select the Guide, then the choices Gather, Ore, and click on the icon of the ore you wish to track. Hold SHIFT and click other icons to track them as well. Then right click the Carbonite map, select Route... and pick Current Gather Locations.
