The Rodeostat has voltage ranges of +/-1, +/-2 , +/-5 and +/-10V. So it can achieve the voltage you want without modifications.
The standard current ranges are +/-1, +/-10, +/-100 and +/-1000 uA. Which are a bit lower than you are looking for. We have made modified versions with increased current range. The limit on this was about 24mA (24000uA). There is a topic discussing the modifications here Increasing current ranges to detect mA
