Exclude files from 'Break at First Line in PHP Script"

I am debugging an application that calls certain files at 10 second increments and it disturbs my debugging of the current file. If I am debugging a file with that option checked, the cron job files get called and my thought process is interrupted.  Is there a way to prevent these files from being part of the debugging workflow when "Break at First Line in PHP Scripts" is checked? 

If not, can we request for this option to be added?

Thanks!!
