[GraphHopper] Personalized paths for user with disabilities

[Account Università Villa Luca]

Hi,
I'm working on a project that revolves around determining paths for 
users with varying accessibility, with GH as the routing core. Our 
intent was to personalize the path returned by GH given the user's 
preferences/ability to some kind of obstacle, such as the inability for 
wheelchair users to traverse stairs or the preference for a singular 
user for some kind of facility, such as pedonal roads. Is it possible to 
do such thing in Graphhopper?
