Sorry mate... I haven't gone through the visa stage, and it seems that I never will. But, hopefully someone here will post the relevant info that you seek. If I were you, knowing that it takes at least 60 days (2 months) for CO to be allocated, I would postpone this documentation to be as near to the 60 day boundary as possible so as to make it look as "current" as one can have. For example, if you uploaded these documents in June, but CO gets allocated in August (lets say), then again CO might want to see a proof of your continued employment for July and August months.
