How can I prevent chunks from being included in IOS .IPA so i can fetch them remotely

Similar to the post here:

I would like to exclude certain chunks from being packaged into the .IPA so I can fetch them remotely using the chunkdownloader plugin. I managed to get a good system working on both android and windows. But I am missing the filters for IOS at the moment that are similar to the OBB filters.

So basically what I am asking is what am I supposed to write in the defaultEngine.ini to exclude certain chunks from being included in .IPA file?
