What is the best way to run an external script on the output generated by textGen from inside MPS?

Hi there,

I'm generation GraphViz .dot files with MPS and I'd like to have some sort of Button for users to run graphviz automatically and generate an SVG.

I tried to create a run configuraton with the `j.m.execution.configuration` language but I don't know where to put it and how to run it (it does not show up in the run configuration menu). Is this even the right approach?
