Not sure if this helps but, I use the Phantom 4 RTK and use a similar workflow. I either shoot my GCPs in an arbitrary local coordinate system with a robotic total station or have a surveyor shoot them in as local coordinates or modified State Plane (which is still basically local coordinates). When a survey point with a real elevation is nearby to pull off elevation, I'll tie into that for Z. To make sure the job processes correctly when Orientating, I always bring in the GCP file as "Local Coordinates". This approach has worked well for me I usually have very little vertical error.
