Currently, when you add a data table from a Data Connection In A Library, the window opens up and all tables within the connection are selected by default. There is no "deselect all" option so it's the chore of unchecking them one-by-one. I have quite a few Data Tables (custom SQL) to get through. In addition, since the list is not sorted, locating the table I'm looking for takes time and risks picking the wrong one.
