double challenge

hello all,
I think that it will be good if we can challenge another player with white/black/random (as usual) and black and white automatically.
Or with a number of game.
For exemple : i challenge xxx for 10 games and automaticall 5 games with black and 5 games with whites start.

What do you think ?

Thank you to read me.
Have a good day.

double challange as in your subject would be nice.
But 10 games against the same player?
That would be boring
