HI we are looking at changing our current support system as the whole SLA / company hours is not very flexible. 

Currently we offer UK support to our UK customer, US support to our US customer and UAE support to our UAE customers over the different timezone, excluding  holidays.

We now have a requirement to offer some of our customer extended support which means that they can get support from any of the 3 offices based on that timezone excluding the regional holidays.

Example ticket gets raised on a Friday at 4am UK time but as its Friday the UAE team are off, we need to setup an SLA that will kick in at 9AM UK time and cover both the UK and US time on Friday and then the UAE time on a Sunday as that is a working day for them. We also need this SLA to exclude all the regional holidays.

Is this possible in Zoho  Desk?
