How do I fetch date from a filename and add it to a column in the file using DSS?
For e.g. if the filename is Test_20170101 and the file has 3 columns test1, test2 and test3. I want my file now to have 4 columns - test1, test2 ,test3 and the new column date, with the value 20170101. How do I do this in DSS ?

Any update on this topic? Partitioning doesn't work in my case (since "Missing partitions as empty" is still not supported for discrete + time partitioning). I could create a new connector for each file in the folder, but this doesn't scale at all. Being able to add the source to the dataset could solve this problem.
