Single post in Mass Trade

I was doing a massive RTE trade of 40 pokemon when I realized that it must be difficult to send all forty of them to another person just like that. I usually send just 10 maximum, but even I get tired after a while. Hence my suggestion: why not increase the number of pokemon you can attach to the trade by a small margin, like 5 pokemon? That way, if I have, say, 20 pokemon to trade, I have to just send 4 trades with 5 pokemon each instead of sending 20 trades individually and getting terribly bored. I hope this suggestion is valid, because I feel that this would make life much easier! Thank you
