Sawtooth-Sin Wave as a new Regular Pattern in FX

Hello everyone,

since i am not quite happy with the Sin Wave in FX, i tend to use more often a Saw Tooth instead.
And it appears in some of the Deafault FX. 

Thiswhile i love to have it as a selectable regular Pattern in the FX Editor.
And just for better understanding, here is the Pattern as a Picture.
