Feature Request – Option to Change Thumbnail Image Across All Color Variants for the Blank Products

I’d like to request a new feature that allows changing or updating the thumbnail (display image) of a blank product across all its color variants at once.

The idea is that when we upload a design like "Your Design Here" or "Your Logo Here", it should automatically appear on all color variants of the selected blank products. This would help clearly indicate that these are customized products only, and that blank (non-printed) versions are not available for sale.

This feature would save time, ensure consistency across product variants, and help prevent confusion among customers viewing multiple color options.

Please let me know if this is feasible or if any additional details are needed from my side. Thank you for considering this improvement!

Thanks
