Is It able to run difference requests with different data files in one Collection?

We have a lot of API in different micro-services , and we are trying to put all request test cases in one collection for one micro-service API. then every time, each micro-service has new release, it will automatically run test cases in that one collection;

But It seems like Postman can only run one collection with one data file and set iterations for the whole collection;
In our case, different request has different data file;
Is it able to set up data file and iteration for each request in the same collection?

Thanks!
