Seeking an efficient way to sync dynamic textures in Verge3D by using puzzles.

Hello everyone! I would be very grateful if someone could help me solve the following issue.

As shown in the attached reference movie, when I press the ‘L’ key, the number on the large square changes from ‘5’ to ‘2’, and the glowing number ‘5’ in the small circle on the right also changes to ‘2’. This logic follows for other numbers as well.

I am aware that I could use ‘Assign Material’ or ‘Replace Material’ puzzles to achieve this purpose. However, since the actual project involves more than just numbers 1–9 (there are dozens of sets), using material swapping feels very inefficient.

Could anyone suggest a better technique for this? Alternatively, is there a specific Verge3D demo file that demonstrates a similar workflow I could study? Thank you!
