Grating drifting in Builder

I am now analysising the visual function of rats. The stimuli should be a drifting grating with a specific spatial frequency. The grating drifts in one direction and then after a specific duration drifts in the reverse direction, in order to eliminate the effect of drifting direction on the visual function of rats.

I would like to know, if it is possible to set the speed or so to speak time frequency in the Builder mode.

Thanks!!
