Lists on the Firestick App

While I have a Watchlist, I actually prefer to do subject lists - like RomComs, Heist films, etc in the app. My Watchlist is just too big to easily make a selection from. But the Firestick App only lets me see the Watchlist. Since they are drawing my data from the same source, can we expect soon to see Lists also available on this platform. I do love it - and IMBDs app is what got me to stay on Firestick versus Chromecast when we bought a new tv.
