You can certainly file to Vacate the child support using all of your facts as a basis. If it is denied, you can then request that you be allowed to give the money to your daughter directly. I am guessing the current Order says it is payable until she graduates from College? If that is the case, then you need to argue that it should be vacated because she may never graduate at the rate she is going.
