OpenPlant Modeller V8i SS6 - Importing a Service by Keyin

I'm trying to expand my model creation vb to import service and unit when a model is created.

I'm using the keyin mentioned here:

https://communities.bentley.com/products/plant/w/plant_design_and_engineering__wiki/8569/how-to-import-unit-service-pipeline-instances-from-a-text-file-to-an-active-dgn-file

But what  I would like to do is use:

OpenPlantModeler Import <Class Name> <Path and file>

Is this even possible? I can't seem to find a way to get the path to work in the keyin.
