You can get it, have done it myself, Main office will confirm but you can't do it through them.
As above, need to have your yellow housebook/tabian baan and pink ID card to do it - this was the real difficult part.
Some offices are very difficult even in bangkok, I managed to get it through the second one after first one would not do it.
Finally trying to setup auto debit for it now as I have to go into bank every month currently, I beleive need to setup a bank account using your new pink ID card and yellow book to get this to work too.
I would possibly ask head office if you need to do in Chiang Mai, if not then go somewhere easier
