Besides not being aware of any, that probably isn’t the best option.
This is the one club I would recommend be done indoors. You don’t want the putting surface to impact measurements like direction of your stroke, or even wind causing direction change. Loft and face direction need to be done from a perfect flat surface level with your feet, to an aim point 10 feet away. There are fitters with equipment like SAM lab setups to produce putter specific data similar to a Trackman used to track ball flight.
