    Design a function that generates all possible delivery path combinations by taking a list of available route types and the required number of route segments, where each path can reuse the same route type multiple times. The function should output a comprehensive list of all possible route combinations, with each combination represented as a tuple containing the sequence of route segments that form a complete delivery path.
