Add ability to append files to "multiple" upload #54
Description
Describe the new feature you'd like
Add the ability to add more files or images to a file input, after files have already been selected. Currently the only option is to remove all files before adding new ones. The best option would probably be to add a prop to allow for adding files/images.
This feature would eliminate the need to re-select all files/images if you missed some on the first time, reduce the amount of uploads (upload-behaviour="live") and gives to opportunity to add files on fields with pre-filled files/images.
This option should only be available to inputs with the multiple prop.
