I'm currently working on a multi-brand product (EHR dashboard) using Figma Pro. I maintain a shared design system for efficiency and consistency, and I use this design system across multiple design files within a project.

For each brand, I need to:

• Create a new project

• Duplicate both the design system file and the product design file

• Customize the design system with unique logos, colors, and typography per brand

The problem is:
When I duplicate the files for Brand 2 and move them to the new project, the duplicated design file still links back to Brand 1's design system instead of the duplicated one. Even if I duplicate the design system file separately, the link doesn’t reset — which means changes made to the design system (like updating Brand 2’s colors) affect Brand 1 as well.

Currently, Figma doesn’t support project-level duplication, which could have helped preserve the file links and created isolated instances for each brand.

My question:
Is there a way to duplicate a design file and relink it to a duplicated design system instead of manully doing it? (instead of the original one)?
Or can Figma consider adding a project duplication feature that clones file dependencies while resetting internal links — especially for multi-brand design workflows like this?

This would massively improve scalability for teams working with white-labeled or multi-brand products.
