How to adjust Fiori in-app help/User Assistant?

Dear experts,

when working with an app, there is the option to use the in-app help/user assistant, marking certain fields with a blue circle and giving the option to display information.

However, sometimes not all fields are marked, or important information is missing. Example: take the app G/L Account Balances. The filters for Ledger, CC, and G/L Account are highlighted, while Controlling Area is not.

Is there any way to adjust the in-app help, so that I can add information on certain fields or highlight them with the circle?

Any help is appreciated. Many thanks in advance!

Best regards

Jan
