compile css without trailing numbers

This plugin almost does everything I need. When the css is compiled it is saved with a 6ish character string after it. I’m guessing that’s some sort of hash. Is there a way for me to modify this plugin so it doesn’t save the compiled css with the trailing numbers?

Example:
What it does currently:
home-template.less – > home-template-43413.css

What I want it to do:
home-template.less – > home-template.css
