Activate Hairworks to collission with Floor and third meshes. possible?

Hello, i’m currently doing a character animation, everything is going smooth, im using Hairworks for the Hair of my character (very long hair) … i would like to know if it is possible to make the hair collide with other meshes , like the floor for example, if my character lays down on the floor, i need the hair to collide with it instead of going through it… is this possible? i can’t find any documentation about it .
