is it possible to add the ability to re-lock trophies?

[Foxee17]

once you unlock a trophy there is no way to re-lock it. i understand it just might not be possible but if it is would it be possible to add?

Once you sync a trophy, there's no way to re-lock such trophy. Data is stored on external servers and that will never change.

So, if you unlock a trophy, you can only re-lock if you did not sync with the official servers.
