How do you add a second time frame within "Working Hours" on the same day for the plugin &

I'm setting up my list of "Providers" and their Work Schedule. Their line of business is teaching. On average they teach 3 programs on the same day but at different time slots. I noticed within the plugin, you can only enter a "Start" and "End". Their customers are pretty picky with time slots and would like to select multiple session on the same day. Is that possible? If so, need someone to walk me through.

THanks!

Awesome plugin!
