KSA Family VIsit VIsa from ETIMAD (Pakistan) - help required.

Hai,
Hope all will be fine.
I was trying to search in this forum about my issue, I could not find any solution so I am writing it.

I am living in KSA. I want my wife to visit here in KSA on family visit visa. I applied online visa on MOFA website and put Saudi Mission of Islamabad.
Now there is no ETIMAD center in my city. its either in Lahore/Islamabad or Karachi.
Can i do the visa process from Karachi instead of Lahore. As there is region change.

Can i go for it or it is not allowed?

I tried to call etimad centers but they are not responding to my calls.

Positive response will be appreciated.
