Change UI Kit variables from Primefaces.org in figma

I’m trying to edit a Form UI Kit from Primefaces.org.
It is made up of components and each component has around 500 variables, however, that’s not enough.

I would like to change the look of all the variables inside the component but I’d rather not go through each variable individually.
I would also like to add new variables to the existing components.
Is it possible to edit the original component so that it updates all the variables at once?
And can I add new variables to the existing components?

Thanks

the entire kit only has around 500 variables, not each component…
i was a little fast there
