Post currency transfer between two bank accounts using different currency from default

Hi all

scenario is as follows - NAV Version2016

3 bank accounts GBP (default), EUR, PLN (polish zloty)

is it possible to transfer an amount 100,000 EURO straight from EUR - PLN without it having to come through the UK default currency.

Currency rates - 1 GBP = 1.14 EURO. 1 EURO = 4.19 PLN. 1 GBP = 4.77 PLN.

So 100,000 EURO's = 419,027.39

Can this be done and if so how? are there specific setups required on the currency in order to be achieved.

OR as I suspect

does this have to go through the UK bank and then transferred from the UK bank to the polish account

Ideas on how best to resolve?

thanks
