Thanks a lot for your help, but this is not what I wanted to know.
Meanwhile I found the solution.
The idea is to copy a sprite and keep its properties.
So:
1. Keep "Control" pressed
2. Select what you want to copy
3. Drag the selection with the mouse
4. Paste the selection to the desired location
5. The copied sprites kept their original layers
YEYYYY! 😁😁😁😁😁
