sort of CSS or ablility to set my variables for watch.

A menu to set colour and mark it as variable A, B, C and D. And then use A, B, C or D in the colour fiels to set a colour. So when i want to adjust colour A all marked as A will change. Basicly a place to set global variables. Might be super usful fo other things to. One will use it for colours, other for fonts, sizes, positions... Almost a CSS system.
