Save a copy of shared board

The ability to save a shared board between accounts is required.
If Person A shares a board with Person B, Person B must be able to duplicate it and keep their own copy. This permission should be controlled by Person A during the sharing process, for example through a checkbox like ‘Allow saving a copy.’  

This capability is critical. It is not only important for collaboration, but also helps address a major limitation in migration workflows. As of today, individual, teams, and enterprise accounts cannot migrate boards between accounts. Enabling users to save a shared board as a copy provides a practical workaround for this limitation.

By the way, this feature was available initially, then it was removed, and no replacement has been implemented for several month. This feature must be available.
