That will probably be no good as your passbook will be updated with 'consolidated' entries if you leave it a certain length of time or number of transactions, assuming that you are doing a monthly deposit.
If using the 800k method, I guess once a year is OK although your IO could ask you to prove that the balance was over the 800/400k limits., and you do not need to show that transfers are international in that case.
Luckily for me, there is a shop called Lotus (or Big C or Central), or a Bkk Bank branch which all have a passbook update machine.
