Third Configuration?

Working on a e-commerce site that has different despatch times, we want to show a count-down to when orders close for the day, to allow next day delivery.
For example: Mon – Fri: 7:30pm, Saturday: 3:30pm, Sunday: 1:30pm
As you can see there’s three different times, At those times, the clock will re-set for the next days countdown time.

Is there anyway to add the facility to allow there third time/day/configuration to the plugin? Client may be willing to pay for the customisation.
