When clicking Add data button in a project, users should be able to choose what data they want from a collection to create a new collection in their project. Say if there's 10 files in a collection and you only want to add 5 of those, you should be able to regex in that pop-up box and only grab the files you need, instead of copying the entire collection, going into that collection and regexing the files you want to create a new collection.
