Bulk import of thousands of labeled training TIFFs for pixel classification in Ilastik

I am trying to train a pixel classifier in Ilastik on a large training set. I have 13K raw input TIFFs with corresponding binary/labeled TIFF images. I would like to use 75% if my data (~9,500) files as training data. Right now, I can MANUALLY associate every raw input file to a labeled training file by manually right-clicking on “Labels” and importing the single labeled file for every “Current View” / raw file input.

Obviously, this is slow and tedious and prone to human error. Is there a way to BULK import all of the raw training data along with associated labels from binary/labeled files? For example, all of my raw files and external label files share the same filename, but are in different directories.

Help? Thank you!!!
