How to specify input data files for ParallelInputter?

I see where you can specify the vocabulary files with vocabulary_file_key, but how do you specify where the corresponding data files are?

With a single file, you have config['data']['train_features_file'] but what about with multiple input data files?

See here:

Ah, perfect, sorry I missed that, thanks!
