Consider providing a configuration file that stores information about mapped variables (e.g. like Figma variables mapped to Kendo variables)
Example scenario:
1. Create a new Figma design based on UI Kit
2. Export it to ThemeBuilder
3. Map the 3rd party or figma-styles to the ThemeBuilder styles.
4. Save the mappings between them as some external config file
5. When I create a new project based on my customized UI kit and I export it to ThemeBuilder
6. Instead of re-doing for a new project the mappings for a couple of hours again by hand, load up the mappings file which I saved from the previous project and the tools just connects the dots.
