My Japanese bank has that drop-down list. When sending money to my daughter in Australia from Japan, it is "Supporting a student overseas".
When I send money to my wife (actually, for our living expenses in Thai, it is ourselves, she is sitting next to me in Bangkok now), I pick "Supporting family". To avoid 250THB ATM charge per withdrawal. I am charged but the charge is refunded back to me.
