I did likewise with Bangkok Bank in Sikhio, Korat. The branch has since been demolished and I'm due for a new bank book & Visa debit card. I hope that doesn't cause any headaches. Initially BB Sikhio said no, not possible. We went, had lunch and returned to the same branch, different staff member, and it suddenly became possible. 🤔
I think if the bank teller you're dealing with isn't familiar with the process, a simple no, not possible is less of a headache for them.
