I have many csv files in one folder that I want to test individually. Now, I am looping through file list and adding one batch definition per path with  
batch\_definition = file\_csv\_asset.add\_batch\_definition\_path()  
This, however, takes ~15 mins for 1500 files. Is there a way to achieve the same goal by adding all file in folder in one go? Thanks!
