We are able to define with File Uploads field how many files are allowed to be uploaded. Now Lets say I want users to upload 2 files. They upload one however we could not provide them hint that you can add second file as well. So I want them to get a hint how to add multiple files if required.

Atleast Add the Button if user only added one and then they want to add one more they should have a way to do it and should know how to do it.

Also give them a hint More than one Files are allowed
