I have yet to find a way to automate things. Either the setting is super well hidden, or does not exist.
While it is a cool mod, the lack of automation in an automation game sadly makes it worthless to use unless you plan to babysit every single space elevator.
I was hoping for something cool to replace fields of rockets, but (in its current state) this isn't that.
I ended up implementing a patch to the mod, to autoconnect, but that only works insofar as you have one item/fluid type moving in one direction at any given planet, and every compatible platform docking at that planet intends to use that flow.
This worked great when my sole elevator route was atmosphere from Vulcanus to Maraxsis, but broke down immediately as soon as I added Heavy Oil export from Fulgora.
