How to create keybind for "Compile for Compact"

[flatlin-e]

Is it possible to have keybinds for both:

• compile with Ctrl+S
• compile compact with Ctrl+Shift+Alt+S

I've tried adding this string into my keymaps:
'.platform-win32': 'ctrl-alt-shift-S': 'sass-autocompile:toggle-compile-compact'

Thanks!
