Splitting VISION into text and video

Hi,

I have worked out using the different data loaders to compare images and video but cannot work out a way to do both simultaneously. It seems using ModalityType.VISION, you can only load and transform either video or still image at one time and not both (from my limited understanding). I think it would be a good idea to split VISION into two types of modality for ease of use. Anyone able to point me to a way to do this?
