How to reset imported data so I can keep on running the labview without having to manually delete data

[BMEchrissy319]

I'm working on a labview that will able to take a text file and read and sort it into the certain boxes on the front panel. I wanted to know if there was a way to maybe wire a button to clear all the imported data so i can run it again without having to take the time to delete the content in each box. Or maybe there is another way to do this. I attached the VI file below and the text file that has to be placed in the text box in the front panel before it is run. I also wired it so you press the run button and nothing is imported until the NOVA RUN button is pressed.

You didn't even try the most obvious thing: Just run it again, the new data will overwrite the old.
