Multimodal network dataset - is it possible to use buffers for changing modes?

i am trying to create a multimodal network dataset, comprising roads, waterways and ports. When i built the network i received the error message "Standalone user-defined junction is detected.".
After looking at the locations of the ports, it seems that the ports are neither located on a street nor on a waterway. So it's obvious why the error message was displayed.
And now this is where my problem starts. How can i use the ports for transit between the two modes? I read in this thread about buffers around transition points but i have no idea how to implement such a solution. I am able to create buffers around the ports, but polygons are not usable in the network dataset wizard.
Or is there another approach for such problem? Any help is appreciated!
