Having the option to set a charge date in the future instead of at the time of registering

Planning future events such a summer camp, I want the families to be charged at the time of the camp / first day of the month the camp is in, etc… Not when they register for the class. It makes more sense for parents and it’s easier for me to make sure everyone is enrolled before hand and I don’t have to scramble to manually enroll everyone the day of so they get charged when I need them to be. It would be helpful if there was a setting when creating new classes that was “charge date” and you had the option for “at time of registration” or “custom” (which would open up a calendar where we can select the date). That way payment gets charged automatically on the date it needs to be but studio owners don’t have to scramble to enroll manually
