Add the ability to wax ledges

Been playing quite a bit and I haven't been doing all crazy stuff I see most players doing but I have been looking for spots that you would be able to hit in real life... But yeah I am getting off track I have noticed that I will find a long rail or ledge and I will try to hit it but I will slow down kinda fast and well I was wondering if there was any way to put in a wax feature so we can wax our own ledges in like rails so they slide better and smoother?
