Invert Y axis only on PS4?

Can somebody please tell me how to invert the Y axis without also inverting the X axis on PS4?

I know I must be being incredibly stupid not to have found it but it's really driving me insane, not being able to play the game I was most looking forward to just because I can't find one little option lol. Please help me?

Go to the Main menu, Sytem then Character Configuration -> Controller and you can inver Y axis there.

Thank you so much!!! You don't know how happy you just made me lol

Seems odd that it was in character configuration and not system configuration but I'm just glad it's in there somewhere :)
