Segments - Chase/Travel - Second Attempt

My first thread on this seems to have taken on a good but different life on a different topic. I am still looking for anyone who might have suggestions on my initial question.

“I am trying to develop a preset that has 3 chosen colors that flow along my led section. I have had fun experimenting with the Noise and Chase effects, however, I cannot size the proportions of my sections. I would like to have a 25 pixel strip of each red and blue separated by a 3 pixel panel of red. I can do the sizing in Segments, however, only stationary. Is there a way to make them travel?”

Thanks for bearing with me.
