GUI: Indicate if a field can be a template (in automation/script visual editor)

[DvdNwk]

Feature Request: add some kind of icon/info/indicator, letting the user know if an action field accepts a template value or not.

Example: I want to send a persistent notification. This is how the GUI editor presents the service options fields:

According to the documentation, both Message and Title can be templates here → it would be great if it was somehow indicated to the user, without having to check the documentation manually, for each service and for each field.

I agree with the request: it was something that confused me a lot when I first tried templates in places that did not support it. I thought I was doing the template wrong.

Maybe you are already aware that all service calls are capable of templates, but not everyone is. And I would like it even more if the number of places templates are allowd increases.
