Multiple camera naming

Hi all. I livestream our church services using 2 x Logitech PTZ Pro 2 cameras. I use OBS for streaming control. When associating the cameras with scenes on OBS they both show as PTZ Pro 2 in the camera list. Is it possible to change the default name of the camera so that I can identify which is which. I have tried going down the route of changing the FriendlyName in registry edit but that change doesn't affect how they appear in OBS. It would seem that they get their name from the PTZ firmware and ignore anything I set in regedit or device manager. Any ideas please? TIA.
