Hello, im starting to use rem instead of px, and i found that with premailer, the style inline only goes with rem units, is there a way to have the fallback to px on the inline version, since some emails like outlook don't use rem?

Exemple:
h1{
font-size:32px;
font-size:3.2rem;
}

It only uses the font-size: 3.2rem, it would be good to use both.

Thanks in advance,
Mário Silva.
