Hi i have 5 services offered by same branch, and one attended. So i want to know how to make it possible not to select more than one services same time...... currently if client chooses for example - hiv testing for 800am, on 23-09-2020,  i have noticed someone may choose same time, same date, but different service...... i want to make for example 800-815 selected once per day despite service
