Automatically update static text according to properties for a text style?

See if I can make myself clear here…

Having a look at the picture below, it has some values describing each heading; size, weight, letter-spacing i.e. Problem is, when messing around with text styles, all these “hardcoded” values need to be manually updated which is quite time consuming.

Is it possible to get these text values to auto update when changes is made for a text style?
