Reverse Lfo (saw)

Guys, it must be a trivial thing to add, a reverse SAW LFO would be very useful.
I use the LFO for filter sweeps mostly, usually for basslines and although the usual bottom>top LFO is nice, a top>bottom LFO would be good also.

It must be really easy to add this feature because the SINE goes from bottom>top then back again… :)
