Template Card - Can you set a material icon to display in secondary information?

[ppastur]

Hi, I was wondering if it was possible to render a material icon using a template similar to the following

secondary: >
  {% set wind_speed = state_attr('weather.openweathermap','wind_speed') %}
  {% set wicon = mdi:weather-windy %} 

 {{wicon}} {{ wind_speed }} km/h

I know I can paste in an emoji however ;

1. emojis don't look anything like material icons that I use extensively through all my mushroom cards and
2. in the future, I would like to be able to change the icon dynamically based on a template.

I know there is a PR #1397 open for something similar but I am unsure if it has been implemented and if so what syntax should I use, if not, will the PR go ahead?

Many thanks in advance.
