How to move multiple documents at once ?

Question

Hello, everyone, 
 Quite new with Appian i' m struggling to move multiple documents at once. 
 I have a form where users can enter some details and update various documents. (first step of a longer process) 
 On submission of the form I have to : 
 
 Create one directory (which depends of the information entered in the form). 
 Upload all the documents in this particular directory.

I was thinking tu use smartservice on form submission but I can only use one in the saveinto. 
 I guess that I could use MNI or process looping in order to solve the issue but is there any better way to do this ? 
 Thanks for your help, 
 Nicolas

I suggest to use a subprocess you develop yourself that accepts a target folder and a list of documents, which can then loop and/or call the move document smart service via MNI, and protect against an empty initial list. That way you can easily test your "utility" subprocess against various use cases, and simply plug it into a parent process when needed. 
 Note: for either MNI or looping, if the list could ever exceed 1000 items, you will need to do something special to handle it. This is rare though so it's usually not worth the extra effort unless you know in advance that it'll be possible.
