No, they're a Irish based subsidiary company owned by a UK building society. It's not just a "branch" of the main building society, but a separate entity. They operate in Euro, in a Euro based country, so of course they're going to deal in Euro.
Their systems and processes are most likely set up to deal with only Euro transfers to accounts within Ireland. The demand for other services, like what you're asking, simply wouldn't be there to merit the time it would take to make the chances for what is basically a very small, deposit holding institution, not a full service bank.
