Creating Test Sets from multiple Test Case folders

Unfortunately there is not a way currently, I have logged this internally as a suggested enhancement (to have some kind of Tools > Auto Create).

Also maybe it doesn't make sense to use test sets in this way, since if you already have a folder structure in test cases, just execute the tests from there. The test sets are designed to give you a way to organize the test cases differently from the main folder list (e.g. to pick and choose test cases from different parts of the application to create a scenario).
