Can’t set default text color variables on text

I noticed I’m able to set a default color (variable) on shapes, so when creating a new shape it uses the defined color (variable). However, this behavior doesn’t work on text. I’m guessing this has to do with the default text color being tied to the color of the page. However, I’d prefer the option to be able to set a variable as the default text color.

When doing rapid iterations, it’s often the case where I accidentally have text unlinked to a variable, and sense dealing with dark grey colors it’s easy to miss some text being black. Tried to set the text to default to my dark grey variable color but it was at this point I realized I was unable to.
