Parameter when calling a script from Google Assistant

Hello,

I do not know if it’s technically possible with Google Assistant,

But it would be interesting to be able to send a parameter when calling a script,

Example:
I have a script:
send_message:
alias: Message
sequence:
- service: notify.notify
data:_template
message: {{ google.param }}

It would be interesting to say:
OK Google, Allume message “Hello”,

I think it’s possible, because when you want to play music on google play, we can specify the music wanted.

thank you,
Cedric,

I feel this should be possible. IFTTT offers custom commands with parameters. I would very much welcome this to call scripts.
