Question regarding the 800K in the bank day of extension transaction type?

I’m going to have to extend the visa soon, will go with the 800K in a separate bank account method for 3 months. (with 5,000 THB extra on top in case of bank fees during the 3 months)
From my understanding, IM wants the bankbook to show the same date as the day I go to extend the visa.
Now in order to do so, means that I have to initiate a transaction on this separate 800K saving account, in order for the bank book to show that the money is in fact still there.
The question is, do I deposit say 1000 THB to the account and make it 806,000 or withdraw 1000 THB to make it 804,000?
It sounds dumb, but I lose sleep even over such small details.
Thanks.
