Before I pull the trigger and purchase, I have a question. I can't water stations sequentially. I need to water station 3 in the morning and station 8 late afternoon. Next day, station 4 in the morning and station 7 late afternoon and so on. I currently can't do this because my current controller is limited to Programs A B C, that requires you to program sequentially. Can I program the stations to run when I want and not be limited by the Programs?
