Finfan;
The easiest way to correct the condition which you describe is to oil the dough balls and then place them into individual plastic bags. Bread bags are an excellent choice. DO NOT tightly close the bread bags, but instead, twist the open end to close it, forming a pony tail, then tuck the pony tail under the dough ball as you place it into the fridge. To use the dough, simple remove a dough ball from the fridge and allow it to temper AT room temperature for about 1.5-hours, then turn the dough ball out of the bag into a bowl of dusting flour and begin opening the dough ball into a pizza skin. This process works perfectly all the time.
