If you would like to upload multiple files, once you get a confirmation that the file was successfully uploaded after pressing the 'Securely Upload' button, you can choose another file and click the 'Upload File' button again without having to re-enter the patient information. You can repeat that for each of your files as needed
Alternatively, you may consider combining them into one compressed file (e.g., a Zip file) prior to uploading
