I don't, sorry.
For context, the ML for Kids site is made and maintained by one person (me!). It's a personal side project that I do in my spare evenings and weekends, and at the moment I don't have many of those, as I'm super busy with work and other responsibilities. The time I do have to spare for ML for Kids is currently being eaten by a major platform migration I need to make, which is frustratingly
turning into a huge piece of work - I really need to finish that before I start on any new features.
As with all open source projects, if you would like to
contribute the feature yourself, you are very welcome to - that is naturally the fastest way to make it happen, as it means you won't need to wait for me to get around to it.
Sorry I can't give a more helpful answer!
Kind regards
