you can sort by alert. One alert shows you have <24 hr left to move, other show you are using you time bank. This shoud be what you want. So it puts the most urgent up top and the least important. Just click the blue alert in my games. Any of the lists headers can be selected to orginize in a way that fits you, then you can progress down the line doing the most important moves first. for more info on alerts see.
