Firefly Veo 3.1 Fast Partner Model Missing Ingredients (Reference Images)

I use Veo 3.1 on Google Flow and Gemini. I also use it occasionally on Firefly but I've realized that the Veo 3.1 Fast option is missing the reference images option, which only appears on Veo 3.1 Quality. What Firefly calls the 'Reference Images' I assume is what Google calls "Ingredients", and it is something I use all the time - much more so than start and end frames. It allows for consistency while not locked to any particular start or end frames.

I encourgage Adobe to add "Reference Images" to Veo 3.1 Fast, like it is available in Google as "Ingredients".
