30 Minute Break Times in Appointment+ Plugin

Checked this thread: https://premium.wpmudev.org/forums/topic/option-for-30-minute-appointment-slots-with-30-minute-breaks-between

But it didn't solve my issue. Basically I need the appoints to work from 9am til 12pm then have a 30 minute break, go from 12:30pm until 2:30pm and then another half an hour break (pick kids up from school) then go from 3pm until 5pm.

How would I be able to achieve this?

I've set the multiple break times to be as above and our standard session times go for 60 minutes under Settings -> General

Your help is appreciated, Cheers Mick
