Question for Saudi National Insurance Co BSC

My car's insurance with SNIC will expire on 31/12/2017. However my car's registration is in November.
I therefore need to change my Insurance to coincide with registration. This means I need to change my Insurance to be from 1/11/2017 to 31/10/2018. This means it will be for 11 months and not a full year. subsequently it will be for one full year.
My policy No. is ********-1767
Please advise.
