Can Haroo Pad automatically switch input method to english when in vim normal mode?

When I press `ESC` to enter vim normal mode, I have to press `Shift` to change my input method into english explicitly, and then press again to switch back when in insertion mode, which is somewhat inconvenient. I think it would greatly improve my efficiency if Haroo Pad could do it automatically for me. Could you please take it into consideration? THX

I'm using Windows 10 OS and my IME is Sougou Input.
