How to enforce healthy gaming breaks within my child’s daily app limits?

Hi Everyone, we have a huge problem with our child being drawn into gaming during her permitted screen time, causing aggravation when asked to pause to do something else. Is it possible to enforce healthy gaming breaks within my child’s daily app limits? Say, if my child had an allowance of 1.5hrs app use across the board and downtime is set between 7:30pm and 7:30am, I want my child to be able to choose freely between the permitted apps, however, want to limit the amount of time that she can game to 30min chunks at any one time. Gaming would be forced to paused and then be released again after 2hrs or so.

any advice would be much appreciated. Thank you!
