Custom voice commands for google home?

hi…

Just installed hass.io onto a rasp pi and did the link to google home mini device using the non cloud method.
It works spledidly.

I am able to control my esp8266 powered hue emulated lights just fine.

The problem is I want to be able to customize the voice commands for my other ad hoc scripts within hass.io.
I see other members of this forum suggest that I use the shortcut feature within the google home app.
Sadly this feature as well as the routine feature are both not available for my region.
Typical huh ?

Any other way of circumventing this effectively ?
I’d rather not use IFTTT if can be, although it should be able to do the trick I guess.

regards
a hass.io newbie.
