How to set color variables ?.

Hi.
Like in other’ design softwares (lunacy,figma), I can define colors and assign it to a variable(ex: brand color, colorPrimary). Then I can use those variable as colors in my design. In future i can change those variable values and it will make at all the places in my design. I couldn’t find such option in Vectornator. Kindly make this feature available.

Thanks.
