Allow selected other parameters to flow with image batches between nodes

For animation tasks, it is useful to pass text and other parameters between nodes. The architecture of ComfyUI permits passing batches of images between nodes, but I wonder whether we could find a way to pass selected parameters as well, such as the text that was used, or the strength of a pose ControlNet application. I have no idea how this could be added to the Comfy UI sensibly, but it might be helpful in reducing noodles.
