Force update of SAT reference files

I am trying to to have an external 3D engine write SAT files and then reupdates and saves the file over and over in a way that is viewed in real time in Dynamo when the SAT file is overwritten.
So far, no luck. Tried periodical run of the graph, didn’t work. I tried creating another dummy input file and switching in milliseconds using periodical graph run between the dummy file and the real file using a python script so as to force reloading the file. It also didn’t work, didn’t respond to updates.
Is there a way to import a 3D file in Dynamo that would maintain a live link with the changes made to the file without having to reload the file over and over? I know it is possible in excel files, just not sure it is not working with SAT!
