Hi Sharon,
I think this should be possible with scripting, but if I take a closer look at your example problem, I would prefer a different solution.
It seems that you need a variable number of timers (including reset and enable functions or so). My preferred first approach would be a functional global VI where you can handle all the settings of each timer within the uninitialized shift registers. You may then use this timer VI at different places on your block diagram for initializing the timers, resetting, en-/disabling, evaluating them. An improved solution could be made with LabVIEW classes.
Regards,
Frank
