Remove or disable output of running task

Hello,

I have  created a buffered digital output using a digital waveform with 24 lines (continuous mode), so it gets hardware timed. while this task executes I need to remove/disable/set low some lines of the running task. How can I do this without loosing the hardware timming?

I've tought of using a for loop to create 24 different task with only 1 line each and put all of them in an array. If any line needs to get disabled I could just stop this task. Do you think it could be a good approach?

Thank you.
