How to keep appending an recorded section?

Hello,
I have a 10-sec .wav file of white noise. I want to keep appending the same section until it is about 10 min long. I used the select, CTRL+C, and CTRL-V method, but the longest section created was 40 sec. Could anyone tell me how I can make it to 10 min long?
Thanks,
Tim

Select the 10 second audio, then repeat 60 times => 10 minutes.
