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.
