Sort of, yes. When I implemented the Dynamic Turnaround Times, the idea was always that players will be able to influence most turnaround activities in one way or another. So you’d be able to pick a different cleaning interval/method/intensity to, say, arrive at a shorter cleaning step. So the foundation is there, I “just” need to get around to implementing all the features 
I figure this would fall under the (rather broad) subject of “Ancillary Revenue”, which currently is merely a placeholder on the roadmap overview, with anything related to particular seat positions or boarding methods in the realm of “probably too much effort given the impact”, but I’m not ruling out anything.
