clion debug configuration

I have a C application that is invoked from command line as follows:

cat input-data | ./myapp > output.txt

Basically, the myapp reads from stdin pipe. I am trying to configure the debug in cLion but setting up a bash pipe seems almost impossible. The Run/Debug configuration dialog does have a box for program argument but entering 'cat input-data' doesn't work.

Am I missing something? 

I can also run the program with ./myapp < input-data  - if that helps
