Yes, you can!
You just need do few simple steps:
- Press Ctrl+Alt+S (Open settings) (anywhere on main screen)
- Search for terminal in search-box (top left)
- change path to : C:\Program Files (x86)\Git\bin\sh.exe" --login -i [change path to yours, this is default one for 32 bit version of git bash on Windows)
- Done :)
- Open terminal and ... ta daam Git bash is there instead of cmd.exe :)
