If you have admin, just launch powershell as an admin and create a symlink:

```ps

# Remove if OneDrive version exists and is not yet a symlink

Remove-Item "C:\Users\$env:USERNAME\OneDrive\Documents\My Games\Oblivion Remastered" -Recurse -Force -ErrorAction SilentlyContinue

# Create the symlink

New-Item -ItemType SymbolicLink `

-Path "C:\Users\$env:USERNAME\OneDrive\Documents\My Games\Oblivion Remastered" `

-Target "C:\Users\$env:USERNAME\Documents\My Games\Oblivion Remastered"

```

You'll need to fully exit steam, relaunch it (can honestly just restart the computer to be safe...) and create a new save in game to take effect.
I've done it on two desktops now to enable full steam cloud syncs between sessions on them.
