"Since uploading results as a whole isn't planned near term, would the same effect be possible by simply going through each player and adding them to a team individually? That's a lot of operations (hundreds), of course, in theory that may work?"
I too would like to know this. Actually, this is EXACTLY what I want to do...Not actually upload blocks, but send individual players.
Any idea if this can currently be done, or any plans of this being done prior to the season start?
