Z-Axis Limit Switch (Cura inverted Z-Axis)

Hi,
I have my Z-Axis endstop set as a maximum (being the top of the printer) but Cura has Z0 be the top of the printer. Right now Z0 makes the build plate go to the bottom. I would like to either: Invert the Z-Axis on Cura (A setting which I cannot seem to find) or change the Z-Axis limit switch from being a maximum to a minimum limit (making Z150 be the bottom of the printer.)
Can anybody help with one of these two solutions?
Thanks!

Change it in the firmware.

The board should have inputs for max and min endstops for each axis. If not, you should be able to change it in firmware. You will also have to change the homing direction in firmware. Don't mess with Cura, it's just a slicer (and maybe control software), this should be done all in firmware / hardware.
