Hello,
The 8.5 beta is now posted.
Details on the 8.5 beta forums on how to check the preview of the feature I have been mentioning, proving it is possible.
It explains scope, what to expect, and how to test for people who wish to test.
When it is ready, it will be released enabled by default.
Feedback is welcome there, rather than on this severely overloaded thread.
Regards,
Alban
