Burn-In node: use value of a connected function or expression as text source

It would be great if there was a node like the Burn-In node with the option to choose the result value of a connected function or expression as text source.

Hi,

I made an image showing how the Burn-In node could work and what it could look like whith the suggested feature of being able to use a function’s or exprssion’s output as text source.
