Can Workbench register changes in individual files when appending multiple csv files in one job?

I recently discovered that you can append several csv files to a dataset in a single domo workbench job - since the file path points to a folder with several files instead of just a single file, is there a way for it to register that only one file has changed and only append that one file instead of appending all the files (including those unchanged)? 

I was testing to see how Workbench handles this scenario, and it seems like it just assumes that all the files have changed and appends all of them. 

Will workbench be able to handle specific files within a folder path changing and only appending those in the near future?
