Can I apply for a Non-O visa extension in a different city with bank funds located in Bangkok?

Non O extension and 800k in the bank and being able to change location? I did a search in the group on moving for my situation but could not find the answer.

Let's say I apply September 1st for a new extension of my non imm. (expires 9 Oct.) But I am still exploring Thailand and I do not know which city I will be in on September 1st. Could be Hua Hin or Chiang Mai or Pattaya or whatever. But my 800k is sitting in a Thai bank branch located in Bangkok ( In early June I will xfer 800k to my existing bank account at the main Bangkok bank branch at Silom to get the 2 month aging started).

Has anyone applied at a immigration office outside of Bangkok using a Bangkok located branch passbook balance and papers?

My first non imm. O extension last September took place in Bangkok and I had to go to the Bangkok Bank Silom branch and have my bank book balance and other bank papers updated/ stamped in the morning and then that same day I had to be per the rules out at Cheangwattana Bkk immigration applying for the extension....it took almost a full day.

How do you pull off an extension with the 800k bank funds requirement when the bank funds are licated in Bangkok and you are applying for an a type O extension in another city?

Or maybe the immigration office in say Chiang Mai or Pattaya would require you to have a bank account in that City?
