Possible to add individual multi-page PDF's in a folder for classification?

[jorkorschool]

Hi, I have the endpoint set up already, but I would like to avoid having to combine all our mail into a single pdf document in order to be classified. Is there a way to change the function so that I could upload a folder of individual multi-page pdf's for classification? For example, we store our documents locally in individual folders (ie all class1 pdf's have their own folder, class2 has its own folder, etc.). Would it be possible to combine these different folders in a zip file, so that they could be classified separately instead of combining them as one document and rely on the endpoint to accurately split them up? Would this be possible with a code change? If so, how?
