Do I need to have 800,000 Baht in my bank account for a year before applying for my visa extension in Thailand?

Because of the current problems many expats are experiencing when transferring their monthly 65k Baht to their Bangkok Bank account via wise not being designated as international, I’m seriously thinking of changing to banked money. Has anyone done this already. If so, do I need to have the banked 800.000 Baht in my account for just two months prior to applying for my next extension, or does it have to be in my bank (my name only), for a whole year. Also, do I need proof of the money coming from abroad.
