Temp control for 2 bed heaters. #55

We are trying to configure the Robin for use in our upcoming 3D printer. We use 2 bed heaters because of the size of the print area. Can you tell us how we can configure the firmware to control 2 bed heaters? Even if it appears to the control software as one, we would like to control the temperature of both heaters. We would be using dual mosfets for the power.

Robin temporarily can not support double hot bed, if directly connected to the motherboard, the power is too large, the motherboard load is a problem. If it is through the external large mos tube, it may solve the problem of too much power, but at present, the motherboard only needs a thermal interface of a hot bed, and cannot display the temperature on both sides at the same time.
