Is there a way I can create multiple sub-labels instead of one by one? I have created the following labels
-2015 -January -3,4 -10,11 -17,18 -24,25 -February -31,1 -7,8 -14,15 -21,22 etc.
Each label and sub-label is created individually, which is tedious work! I was wondering if there is a quicker way to add multiple sub-labels all at once, instead of creating one by one by one.
