I have been looking over the pragma documentation and I cannot seem to figure out how to create a multi-parm UI widget. I am putting together a new tool for my MA Project and a good portion of it rest on the ability for an artist to add in multiple the main UI portion and then the code will layer them together and process it. I have used multiparms successfully in the past, but not with VEX or Python, just expressions and genearl nodes. How do I create one programmically?

I just created the UI I am looking for roughly with the interface editor.
