Expand Collection exponentially based on Swagger file

Hello All,

I am building a Collection of test cases (about 50) to run on over a hundred of our internally developed applications; the teams have all the APIs in Swagger. I am looking to take the test cases I have created and expand them exponentially so each API in Swagger goes through the full test Collection. How do I get Postman to do this? I am not finding any way for this. The closest I have found is using the Swagger file as input for Data in Collection Runner. FYI: Once this is tested it will be ran by newman in our CI/CD setups.

Thanks for all the help.
