Huawei P10 lite Change Mobile Data Calendar

[AC Question]

Hi, I'm having trouble changing the mobile data calendar on my Huawei P10 Lite. I want to cap my data usage so I don't go over my monthly limit. Problem is that my cell phone billing cycle is from the 20th of the month to the 19th of next month. The P10 Lite is calculating data usage from the 1st to the end of the month. I can't find a way to change the setting so the phone calculates data usage the same period of time as my actual billing cycle. Any way I can do this?
