How to block specific apps on an iPhone

I'm having a hard time configuring my daughter's iPhone with Screen time. I would like to completely block some apps during the weekdays and allow some time for them during the weekends. Screen time only allows me to set a limit strictly greater than 0, so I have to set all the apps I want to block to 1 minute. Knowing that she can auto-extend for 1 additional minute, an app that I want blocked has instead 2 minutes of usage per day (not a big deal but still...). There is a "Always Allowed apps" list but not a "Never Allowed apps" list. Uninstalling the apps is also not a solution as I want them available during the weekend. Is there a way, with Screen time or another app, to have a better control and put in place what is described above?
