I am wishing for a way that Iclone would have a step function, or sine, cosine, ramp etc.... function that can be used to drive a value in a periodic fashion. 

For example, I am simulating a red light that brightens and dims in a periodic way. Instead of having to go to the timeline and add all this points, it would be great to call up on a sinusoid function that has a 2 second period and an amplitude of "x" and have that drive the brightness value of a light from time T1 to Time T2. That would  eliminate the need for having to do this all manually. If this is covered by the graph editor the disregard...
Cheers
