software needed for trading multiple accounts

hi guys,

i need software to allow me to log in to and trade (not in-running, just outright) separate betfair accounts at once. i need to be able to allocate a portion (or an amount) to trade from each account per click and for there to be a single interface that enables me to do this, so i only have to click once per bet, as opposed to logging into multiple accounts and flicking between them at speed.

does anybody know if this is possible? and if so who makes it and what is it called.

thanks in advance
