Open Orders/Tabs Tracking in API

Does anyone have an update as to tracking quantities sold and orders in open tabs/tickets? This has been a much requested feature over the past 2 years, but I haven’t seen any mention of this feature request since.

We work with about 20 other POS systems, and all of them have this feature.
It’s a necessary aspect of many apps and 3rd party products. Thank you

Just adding here that this has been previously requested in a few other threads
