How can i use clamp() for font sizes? Any chance of supporting this in the future at least in the Global Style section

Beaver Builder

Do i just have to use hard coded CSS to use clamp()?

What is the best method for doing this?

h1 {
font-size: clamp(1.5rem, 4vw, 3rem);
}

I would love it I could enter this in Beaver Builder. If the font size could have a option to support strings.
