How do i create folders for layers?

Hi Solidworks User's!

I'm trying to create a rather large master template where configuration of components can be changed by just switching layers on and off. However this will use A LOT of layers, somewhere around the 200 - 300 mark so would really like to create a few folders for them. i.e outer, inner, parameters etc etc.

Anyone have any idea on this?

Massive thanks to any help given!
