Temperature offset on heat bed

Is it possible to add a temperature offset to the temperature reading from the heat bed? I tried using the M912 command and it did not appear to do anything. I am on firmware version 1.18.
We make a lot of machines, and use a lot of silicone heat mats. The thermistors vary slightly between batches leading to readings being off. I would rather calibrate with an offset of a few degrees on each machine rather than trying to figure out proper thermistor parameters for every (slightly varying) heater.
M912 is for adjusting the CPU temperature reading. To adjust the bed heater reading at room temperature, I suggest you adjust the T parameter in the M305 P0 command.
