         The control dataset needs to have files that match the filenames of your training dataset. They should be
         matching file pairs. These images are fed as control/input images during training.

+        <br />
+        For multi control datasets, the controls will all be applied in the order they are listed. If the model does not
+        require the images to be the same aspect ratios, such as with Qwen/Qwen-Image-Edit-2509, then the control images
+        do not need to match the aspect size or aspect ratio of the target image and they will be automatically resized to 
+        the ideal resolutions for the model / target images.
