Resource Scheduling - Timeline

Hello! I have checked previous posts but couldn't see anything which related to my question - currently the Resource Scheduling timeline gives an option to change the view by Day/week etc but is there a way when Day is selected to break this down into half hour slots rather than hourly as it does now? We have Creative agencies who work on quick turnaround jobs which typically last 30 mins who would like to use the Scheduling but this is holding them back? Any help is much appreciated!
