Rollercoasterscenery and Events

Would it be possible to arrange that the Rollercoasterscenery (Not the waitingline) and (in case you added) eventtriggers could have please an effect to the RC parameters?`(Increase the joyparameter). Like it does too to the waitingline.
At the moment it is mainly pointless if you give your coaster a nice scenery and loor, or if you simple crap them into the landscape. I think in a game that is so mutch aligned to detail decoration this should be added into having an effect. Especial due the fear and sickness parameter do kill your funparameter in sutch a super hard way. A counterwight would be very nice.
