I know there are a lot of other priorities and requests right now, but It would be amazing if in "Test Day" you could select a specific section of the track to start out at. I find this would be very useful in mastering specific corners and then be able to restart again from same section. Repetition and building muscle memory are key to skill building. I use the technique of chunking and breaking down things into learn-able bits to develop muscle memory in another discipline and find it very effective.
