A method for grouping hydraulic functions associated with an agricultural implement includes accessing parameter data associated with hydraulic fluid used to drive a plurality of hydraulic functions of the implement, the hydraulic fluid being supplied from one of at least two pumps. The method also includes determining delivery pump pressures for the pumps for each of a plurality of different pump/function combinations based at least in part on the hydraulic parameter data and determining a power parameter requirement for the pumps for each of the different pump/function combinations based at least in part on the delivery pump pressures. In addition, the method includes selecting a desired pump/function combination based at least in part on the power parameter requirement, and controlling an operation of a plurality of switching valves such that the hydraulic fluid is supplied for driving the hydraulic functions in accordance with the desired pump/function combination.
