Performance improvements coming to the New Table Report Style

Has there been an progress on being able to show subtotals when new report groups are collapsed??

I have been asking about this for a while and I recently found this in the community:

"

As a marketing / feature end of life story by Brian Cafferelli from 12-21-2020 it stated that

"We are also exploring improvements to the collapsible groups in the new table reports, so you can collapse all groups while still seeing the subtotals. That is a change we're considering making as a fast-follow after new table reports become the default in Spring 2021."

At this time when you collapse the group the subtotals still disappear. Is there a way to activate this feature, or is it not live yet"

Thanks for your help! I am hoping that this feature is coming soon so that New Reports will finally be usable.
