Since the change to the Service Web UI, I noticed that we have broken custom rules due to the added limitations put in for the days.

Currently our on call rule shows as follows:
Mon, Tue, Wed, Thu 04:30 PM - 08:00 AM
Fri 04:30 PM - 12:00 AM
Sun, Sat all day

You will notice that Monday at 0000h (Midnight) to 0800 is missing.
However according to the interface, we are unable to add any additional time blocks without adding a completely new custom rule. - In this idea, customer can create multiple custom rule in a day in very extension without creating another new custom rule
