Dynamic Input - Rejected files

[JamieHankins]

Dynamic Input should either:

(a) have the option of merging files with different field schemas

(b) Return a list of rejected filepaths

One of the problems I have with using Alteryx is the frequent need to input a bunch of files, but a few have an extra/missing field. The extra/missing field is often unimportant to me, but it means that the dynamic input doesn't work.
