Data Usage on the Start Screen

My family uses a family plan, but we have separate data plans. However, the account is registered under my moms number, and her number is the default in the MyAt&t app. Because of this, I have to go through a series of different screens in the MyAt&t app to view my own data usage for the month. My question is, is there a way to either
1) set the default number on the app to my own rather than my moms number?

Or

2) to somehow pin my data usage to the start screen?

Any help would be appreciated.

Unfortunately, its whichever number was first registered online to access your account, that becomes the default number. Maybe try calling AT&T and see if they can change it around?

Thanks for the help, I might try that.
