Does USB-C passthrough to saddle on WD-20P work for external PC

On my main pier, I run a standalone PC beside the mount and not a mini PC on the scope. Wonder if anyone who has or knows the WD-20P can confirm if the saddle USB-C passthrough works in this direction. It seems fairly clear from the specs that an OTA mounted mini PC can route through and control the mount. But my need is an external PC to connect to the mount, route through the saddle, and then hook up to a control box on the scope. Thx
