Import Batch of Files

Hello, I am a mentor for an afterschool robotics competition called FIRST robotics. We have been given CAD files of our kit of parts (KOP) however, they all the files are either in Inventor or PRO/E formats. Is there a way to import the KOP library into solidworks? Solidworks does a good job at importing PRO/E files but there are ~350 parts and doing it one-by-one is tedious. Is there a way to do a batch import of the parts?
