Resolved! In STM32CubeIDE, can I add python script to auto-run before compiler runs? To increment a BUILD number in *.H file.

In old AC6 workbench, I could add such python script as external tool to auto-build always before compiler runs. Now with STM32CubeIDE, I've found how to do manually with 'external tools' button. Can I add back to project to auto-run again?
