Why is Adding Brushes to Libraries ridiculous?

thought i would add some brushes to libraries now ive got CC, to start to use this year, i cant belive i had to drag and drop EVERY single brush and that you cant just bulk add to libraries!, you can even shift and highlight all brushes but when you go to drop into libraries, it only copies 1 brush... what a ridiculous way of just adding brushes to libraries,  why isnt it simpler? , also could have brush folders within folders etc,
