Standard asset First Person Controler sprint

I’m using a standard first person controller for my game. I found out that there is sprinting on left shift. The problem is that my character can sprint backward as well as sideways.

The question is, how can I make it run only forward? Something like double button input, left shift and W. I checked the code and it’s complicated. There is something with the left shift input, I tried to make modifications to it but non worked.

Resolved. Thanks for no help
