As the title and descriptions says

The cook at camp mcarren asks to get some trade routes established from the various merchants about, but there doesnt seem to be any dialogue options to actually trigger the negotiations of a supply route, is this possible or something yet to be released? If its yet to be released, why? surely it isnt that difficult to sort out a few scripts to establish trade between mccarren and other places?

Being that this is not in the spoiler section I will just answer that the dialog options are out there......
