The renamed well path name is serialized correctly, but reopening the project reloads the source well path file and overwrites the saved name with the name from that file. The reload flag only protected the completion export name, despite the loader also updating the displayed well path name.
Only initialize the well path and export names from the source file during first import. Subsequent data reloads preserve the names stored in the project while continuing to refresh geometry and metadata.
Add an RMS well round-trip test that renames an imported well, saves and reopens the project, and verifies that the custom name is retained.
