I have two questions on Baggage Files.
1. Is there a limit to the number of Baggage Files I can add to a project?
2. Is there a way to batch upload multiple Baggage Files?
As to limits, there are none I'm aware of.
As to uploading, if you have version 2017, there is! You can point at a folder and add everything in the folder as well as any sub folders.
But I see you are reporting 2015. so sadly you are limited to simply clicking to select multiple files and adding them that way.
