Add websites to parental control settings

In the parental control settings it is now only possible to add a website, app or game from a predefined list. I would like to be able to manually add websites to this list as I am using the parental controls to prevent getting distracted by websites during my workday.

As mentioned by others, the schedule is now much to limited as it is not possible to have multiple schedules per day (eg. one hour in the morning and then again during the evening).

I am now using Freedom.to to set fine-grained schedules for when to block which websites and apps but it would be much better if I could use NextDNS for that. I would even be happy to pay for this as a paid add-on.
