How do discard changes to local workspace but not server workspace?

I must be missing something super simple here, but how does one discard the changes to an object in a local workspace without losing the changes in the server side workspace?

Steps to reproduce

1. Check out object
2. Open in Creo, make changes, save.
3. Upload changes.
4. Make more changes in Creo, save.

Need to discard changes in step 4 and return to condition of object in step 3.

"Update" doesn't work - "Nothing is Out Of Date in Workspace"

Frames (or events) aren't an option (in this particular case).

Current workaround is to launch Creo on a different PC, export the object from the same workspace (with only the server side changes), physically transport it to the other PC, and re-open, overwriting the last local workspace version.

Is there a better way?
