I like to know how to change the order of stickers please.

By this I mean the following.

I click on sticker spray bottom left, i have preset already open with a list the first is the sticker spray i then go into the group sticker spray and then into the drop down menu and then click on the ones i like in the folder of my name.

So I wish to simply drag the folder i use most to the top so i can be more productive and selective over the folder and brushes, can this be done and how please?
