Indirect work has been getting done on groups that can lead to this being possible, but direct work on this hasn’t been done yet.
Groups aren’t all that easy to make happen and they also aren’t easy to make performant so our current work has been optimizing those types of aspects that will hopefully pave the way for other improvements like this in the future.
Sorry it’s not better news at the moment, we just have some foundational work to do first. It’s not a forgotten request though.
