I'm working with a company that regularly receives large comma separated text files from external parties ... large as in 2-300 columns. It would be nice with a couple of features for specifying column data types:
1. Based on the first X rows (where X is user specified), Discovery Hub could make an initial data type suggestion, just like when we import data from a file in SSMS.
2. Multi-selection of fields (the usual Ctrl and Shift functionality) to update the data type for all fields in one go, also like importing text file data in SSMS.
