I just gave it a quick try and you are correct it works in the library global object preview but not in the MVO settings itself.
I assume it is something that will need to be programmed into the MVO settings dialogue to allow this to work.
I will try and get a request off for version 21 while I still have access to the testing forum.
I think it would be a good idea.
