This is a pain to do manually for any more than a small number of turns. 
However, it isn't too difficult to programmatically define and assign 
the currents with a loop in a lua script.

I've attached an example lua scipt that does just this. It draws an 
air-cored coil with 100 turns. Each turn has its own current 
constraint, forcing exactly 1 amp to flow in the turn. All of the block 
labels in the coil are defined to be in group 1, so you can use the lua 
command groupselectblock(1) in the postprocessor to select them all in 
one step, e.g. to compute the total losses including proximity effects.
