Save Symmetrical file-piece

[onoffdesign]

Hello everyone.
It is possible to save one symmetrical file-piece from another piece and they are linked. If we make a change in its origin, is it made in the other symmetric ?.

Thank.

You have a much higher chance of getting a useful answer if you can provide some ore detail, such as a screenshot, screencast or even share your model.
