The directory I would like to host on playfab/content/filemanagement is only about 52 mb, but it is taking over about an hour to upload. This is due to the structure of the directory being many, small files. For each file I am currently making a request to 'getcontentuploadurl' and then actually making the upload request. All of these requests are starting to take a lot of time. Is there a way to make one getcontentupload url request and then upload a directory to it?
