Allow users to add their own .txt files for images on trainer

So I have been recently using the trainer to train flux models. I actually like the trainer and I would use it more but it has one big issue. The big issue I have with the trainer is that I can’t put in my own .txt files. You only have the option to manually input every caption or use the auto tagger. The auto tagger works well but it only does 30 tags, that’s not a lot and especially with flux, you want to be super descriptive. So the only choice is to manually enter every tag in from my joy captioned .txt files. This is a tedious task, especially when you are working with 50-250 images in a dataset. If there could be an option to allow us to upload our own .txt files it would be very much appreciated and of course I would spend more buzz to train :)
