Using STM32IDE, is there any way to enter preprocessor defines, as currently when regenerating code from the 'Device Configuration Tool', any defines entered manually for the project appear to be deleted?

I'm thinking in particular about defines to influence the HAL library code e.g. USE_HAL_TIM_REGISTER_CALLBACKS.Adding user defines in MX just puts them in main.h and they are not seen by the library code.
