Option to duplicate the color combination for new template

This is a crucial feature that could save a significant amount of time. When selecting a template from the Public Library for a mockup, we can currently add color combinations using the color picker tool. However, these color combinations are not saved.

It would be beneficial if we could store these combinations and automatically apply them to new templates when needed.

At the moment, it's a manual process to apply the same color combinations to multiple mockups for the same product but with different styles.
